Let's be honest the game is quite easy. However, I really love the cute graphics and the idea of using "the power of liquids". The game obviously lacks audio, and maybe you could have make a bit less levels and have a basic audio loop or some sound effect when pouring liquids. Overall I really enjoyed the game, great job :)
The graphics are great, and and I like the central mechanic implemented. I can imagine with extra jars and more movement options, the game can become a very interesting puzzle game. As it is right now, the limitations makes the game super-linear and repetitive. I also found the act of refilling, walking to a pit, then pouring the liquid, and repeating that process over to solve the puzzle boring and repetitive as well. More time spent on the games level design and controls would have probably made this game more interesting.

I played this game on stream with @omiya-games.
I think that the mechanic is unique and cool. The current state of the mechanics leave it feeling kind of incomplete. The puzzles could have been made much more substantial by expanding the mechanics. For example: giving the player reason and ability to under-fill a ditch, overfill it, drain a ditch, or create a 'bouncy' liquid that could have added some light platforming.
The ditch-filling mechanic isn't completely bullet proof, but it works well enough. The art works. Just implementing the game as it is in the time limit must have been a substantial challenge. The presentation itself, save the lack of sound, is solid.
