That was actually surprisingly fun! I'm so glad the controls actually feel like tetris and even tho I'm not usually a fan of 'fake tetris blocks' like the one or two blocks being used in tetris clones, I think it was fair enough to be added in this one. I know this might have been added in to prevent softlocks but I think it's really funny that you can clear lines in this game too. Also I'm glad crushing the guy doesn't actually crush him and he moves to the next available spot instead.
Might have been a little too short tho but that's such a nice feeling after having just reviewed two games that took me an hour each to beat. Some variety would've been nice tho. Maybe an endless mode where you're just trying to build as high as possible and the water starts increasing faster and faster.
