Fireboy & Watergirl: Elements

One of my favorite games.
Pro tip: If your display refresh rate is higher than 60 Hz, the game will run slowly. To fix this, set your display refresh rate to 60 Hz. ;)

worth the eur, works with steam remote play (make sure to change ur monitor hz to 60 also the all green achievement don work)

puzzle game which works with steam remote play together. make sure your monitors refresh rate is set to <60 fps and youll have a jolly time with a pal of your choice. fun game to 100% except the bottom left crystal level ♥♥♥♥ that one

Overall a pretty fun game to play if you have a friend in computer. With the exception of a couple of levels, the game is fun to 100%, at 79 cents i would honestly say everyone should give it a shot.
The main issue are the glitches. You technically can't get the 100% achievement if you don't use SAM or change the files, the game is unplayable if you have a framerate over 60 Hz. Here's to hoping these will be patched soon!

Another classic flash game added to the completion list.
The controls are pretty straightforward: Arrow Keys to control Fireboy and WASD to control Watergirl; bring both to their respective doors while avoiding stepping where you're not supposed to and collecting diamonds to beat a level; fire can't touch water, water can't touch lava, both die to the green goo (acid?); if it is not clear yet, it's a platformer.
There are level sets that focus on specific things, such as:
Leaf - All-rounder;
Water - Watergirl does most heavy-lifting;
Fire - Fireboy plays platformer builder for Watergirl to jump over lava.
Sun - LASERS!
Crystal (ying-yang) - Portal 2D
Wind - Fans (duh)
Ice - Snow, slippery for Fireboy, slowing for Watergirl
There are also two level types: Normal, that reward you for completion, getting all diamonds and for time; and Diamond, that reward you for completion and getting all diamonds (including the big white one), but no timer, so take your time solving them.
Altough this game was designed to be a COOP, where two players play each character, you can also try controlling both at the same time (possible, I've done it). Have fun!

Now, for the achievements:
Only two, unfortunatelly, and one of them is unobtainable. Beat all levels with the Green Gem (so all collectibles and within the time limit) can only be acquired by executing a command with devtools. If you beat the game fair and square, go ahead and use the command, the devs are not coming back to fix their mistake.

It was really fun playing with a friend and solving the puzzles was a blast

Game of my childhood, only think is I didnt get both Achievements and I dont want to use dev tools to fix it
