Very cool game and I love the artstyle! There were some bugs, like a vase clipping in the floor if you go to the upper left corner at the start, or being able to go out of bounds by crossing the water after getting the spring upgrade for the first time.
I also couldn't find a use for the light, and springs weren't completely visible in water.
The explosion was very fun to use, kinda wish there were more things to blow up.
This is an amazing game for only 4 days, well done!
