Really enjoyable concept, and a good use of the limitations! At its core its a really fun idea. The art style is also awesome, gotta love the isometric look. The character and enemy designs are also all really cute! The music also sounds brilliant.
Tho at the start it was really difficult to read the tutorial texts, they were just far to small. It also took me a while to figure out how to use / what the water cannon did. But it was really fun regardless, great game!
