Spacious Snake

A short puzzle game (10 minutes or so) but it is a cool one. It looks like a starter project for someone learning how to make games so I will take that into account.
Things to improve:
An undo button would be greatly appreciated.
The order of the levels is quite odd since the difficulty sometimes drops significantly (e.g. level 18 is super easy).
You get the final achievement when reaching level 20, and not when beating it which is odd.
There are some graphical glitches regarding pixel alignment (the weird line that separates the snake every now and then). They can even be seen in the screenshots. It is not that big of a deal but it is something to polish.

Tiny tracing squares type of puzzle game
A common puzzle game, in Spacious Snake you're a snake that grows and has to fill the whole box with its shape, while only allowed 90-degree turns.
There's a small twist that there may be pushable wall squares that block your movement in that direction but they nevertheless need to be filled as well.
While a neat collection of puzzles, it's extremely short and quick to complete: it took me just 7 minutes to complete all 20 levels. There's also a cheat code F7 key to auto-complete levels, which further diminishes the point, as it can be used to gain the Steam achievements.
I liked the game but it's too short, even for sub-€1 game. I think it should be free instead - it's hardly even a game snack. I'd cautiously recommend it but with the aforementioned caveats.

Twenty levels of guiding the snake to occupy the entire floor of the level. It's a very short game which you can probably finish it within 30 minutes. The difficulty increases as the levels go higher but sometimes, it can be as simple as level 1. Nothing else I can mention this game since it is too short and the game is exactly the same as shown on the video.

Very relaxing game, the puzzles made me think a little but not too hard. It presents new mechanics regularly keeping the gameplay fresh!

I probably wouldn't have gotten the game in normal circumstances, but I wanted to deplete a card I had with some cheap games. This game is great, worth the price and the 7 minutes it took to finish.

Cheap / good for kids
Im experienced into puzzle games but I thought this would take more than 8 minutes to finish.
20 easy levels to beat. if it had more, and more complicated levels that would be nice.
It's cheap, so I'll leave a positive review because it seems good for kids.
If you want a challenge try Snakebird.
And now i'm left wondering why there are screenshots of technically impossible levels (that thankfully are not in the game) on the store page?

I really enjoyed the little bit of time that I spent on this game, the puzzles weren't even that bad. My only complaint is that there are only 20 or so levels, for $1 it's good, but I would enjoy some more levels. If you have an extra dollar to purchase a game I would recommend this for sure!
