BEATris

It's an interesting take on Tetris. I wouldn't say it plays like a rhythm game as you don't have to do anything in sync with music, but it still plays quite differently. In the fastest songs, it requires a lot of attention to look at what is coming next and what is on the grid, and getting in the flow feels really satisfying!
What bothers me are the songs in which the grid moves "at random" (in rhythm, but in unpredictable directions). Except by replaying the song a lot and knowing it by heart, there's no way to guess what will happen and how to place your blocks well. This is a major flaw to me, but it's not found in all songs; otherwise, that would be enough to make me not recommend this game.
There's not a lot of content as of now, but there are some decent songs out in the workshop; so if you're willing to search for new songs, it's a good deal, especially at the low price of about $3.

Just got this game through the Rhythmfest.
I haven't played a lot of it as of writhing it, but it's already clear to me that it's a shame this game doesn't have more eyes on it. I wish I had seen it sooner. I love Tetris and block games on average, and this is an interesting spin on the formula. Lining up your blocks to the beat, the stage scrolling up and down or side-to-side, blocks pushing blocks, a bonus meter that affects the gameplay. It's all really cool ideas and it plays together really well as you wrap your head around it. The music is really catchy and feels familiar even though it's all new to me, and I'd actually consider paying for the soundtrack if it was available.
On the accessibility side of things, I LOVE the visual presentation. Everything is distinct, easy to read, and leaves no real room for confusion once you've played a few rounds,. I do wish there was more options for controls, or controller support, but I won't harp on that too much for such a small, inexpensive game.
While I don't think this is a game that I'll spend hours at a time on, I can easily see picking it up for a song or two a few times a week. If it did have controller support, I'd even take it as a portable game on my Steam Deck while commuting since I don't drive. Even without that, I recommend the game for just about anyone to try!

As a long time fan of puzzle games like Puyo Puyo, Tetris, and Puzzle Fighter along with playing rhythm games all the time like Beatmania, Project Diva, P4DAN, and even old stuff like Vib Ribbon I really gotta say that this game is hard as fuck. You have to be able to think super freakin fast in order to keep up with the beat of the song and even during the first real main level after the tutorial I was already struggeling. Unless you're already pretty good at these kind of games I really do have to tell you to just stay away. However if you love rhythm games and puzzle games and think you're pretty good at them, then come on in and fill up the workshop, it's pretty empty being a new release and all that :)

This game is worth trying if you are a fan of rythm games, like myself. However, the community of this game is very small, which is seen by the number of the songs available in the workshop. Also, the last updates of the game were in the September of 2018 and I really hope this game will be developed further because I think the concept is very good imo. In the end, I wish that the community will grow bigger since at the moment it seems to slowly die which is seen in the amount of new songs made.

recommended for the graphic, the music, the fun mechanic, and the fast evolving devs!
it's great that custom controls and DAS/ARR options has been added! (though the repeat delay 0ms works like 16ms and 1ms works like 33ms... hope this can be fixed. speed matters! 0ms might need some special processing, but that's the key to speed!)
though it's just personal request as tetris player... another option "always spawn in the middle" please?
imo, the reflection of muscle memory built based on how many grids to move highly depends on the predictibility of the block's position. but for example, a vertical "I" piece near the side, after dropping, another I-piece enters horizontally, there will be a "kick-in" move? that's just some unexpected move (or say the move is not from myself).
also the "instant middle" button can be omitted this way.
more detail, the double-bar (red) on the I-piece is hard to distinguish from ordinal red block... may consider adding some border or more shiny effects?
moore suggestions
highlight the grids that will be pushed down in the screen, according to the current piece('s shadow). because, well that's another personal opinion, it's not quite consistent with "physical intuition" that, a grid of air (blocks on the ground not contacting with the dropped piece) can block the force that pushes a whole column down to the ground.. a highlight may help getting familiar with the rule faster.
make shift left/right event visible in the next window. won't there be experts who can read that ahead?
other transformations... well that depends on the level maker's conscience.
a second or even third next piece, equally distanced, shown above the shadow or somewhere. (there's an old tetris-like game named "quadra" doing this, also available in nullpomino)
because the blocks shown on the right depends on the pace and may be overlapping.
overall, maybei have some different concept... like, the "messy gameplay" is accepted by the designer while i hope things to be more under control... so these are just for reference, but of course i'll be happy if things changed this way~

Do you want a puzzle rhythm game where you can scream the whole time and still have boatloads of fun all for the low low price of 3 dollars? Well this is your game. That being said there is a severe lack of content in the game that I hope will be worked on during the early access. I'd also love to see some more effects. The music makes it very satisfying to drop blocks, but an added visual element would be great. I'd also like to get some sort of sound on the failure screen. It's kind of jarring to go from tasty jams or finishing a song to just nothing. Even some cheering after a song would really help out a bit. Lovely game though, I'm excited to check up on this game every now and then to see what new stuff is offered~

Very interesting idea! Its tetris, but to the beat of whatever song was put in for that level. The controls are weird to get down (at least for me), but the power blocks make this game a lot more forgiving than it could of been. The power blocks will push down some gaps youve made before. I personally had a lot of fun on the first moving level. The moving parts really add to the chaos of the game! I hope this game continues to move up and get worked on further because so far its pretty fun.
