Very nice puzzle game! I haven't beaten it yet but it looks great so far!

Meh,didn't understand

beat it, cool game!

I made it to level 26 before I lost my mind over the slow movement

Pretty nice. There are a few things that I think are not incredibly great:
1) The instructions at the beginning. If some people strive to understand a given mechanic, the best solution is not a wall of text, but levels that introduce these mechanics, one after the other, in a proper way -- aka, if one of your game mechanics is misunderstood by some players, this probably means that you could introduce it in a better way. Now, some players might feel overwhelmed before level 1 even starts, which would be a shame as there are actually pretty few things to understand.
2) How water behaves. I mean, it makes sense that it is slippery, but with a sponge, you can somehow move block by block without slipping AND without the sponge absorbing the water (and probably fading away into oblivion, just like it does when cleaning up oil/dirt). The only places where I stumbled for a minute were those where this mechanic was used, because it still did not make any sense to me by the end of the game.
3) Music. It's not that I disliked it, it's more that I got very tired of it. It's a pretty short loop that you will be listening to for 40 whole levels.
4) Levels 39 and 40. I get the general idea, but just turning soap collection into simple cleaning duties would probably make these less tedious.
There were also a few places where the water did not serve any purpose whatsoever, and moving speed is arguably a bit slow.
Apart from that, the game really delivered what it promised: simple fun. The near lack of a difficulty curve is not something I would criticize the game for, because I enjoyed just cleaning stuff and repairing sh*t without a care :)
