A lot of puzzle games this time, which I wasn't expecting. I like puzzle games but I am terrible at them.
I love the intro and the pixel art in it, though the delays should probably be shortened a bit. I skipped past it the first time because nothing seemed to be happening.
The ingame tutorials are a nice touch, but the instructions are somewhat unclear. I didn't realize that allowing water to touch a gem would recharge you in addition to purifying the water. The format also has the disadvantage that you can't go back and reread what you may have missed.
I didn't finish the game; I couldn't get past the water puzzle with two gems in the room with very low water and a third gem several blocks away. I though it would be easy- place block, jump on block to get gems- but I found I couldn't jump on the block. Not sure if it's a glitch or not. I was almost able to beat this by manipulating water levels but couldn't quite figure out how to make it work.
I love the use of water for puzzles, but I second that the water really needs an animation, and sometimes water levels change in a way that seems unintuitive based on your actions. I also agree that the game shouldn't allow you to waste charges at all.
The platforming controls are just okay, but I realized quickly that this isn't a game that lives or dies by it. As far as I can tell there are no sections where you need to be quick and precise to not die horribly.
This game is definitely hitting that length where the lack of quality of life features hurts it. I really wish I could stop and come back to it, but there is no save or level select of any kind.
Overall it's a charming and fun little game.
