Neat puzzle game.
Clever mechanic and game design making you balance score per second and time. Art style is very pleasent, and puzzles seem well designed. Quite a unique take on the Jam Theme too.
For improvements, as others have mentioned, stone villages are a bid confusing at first. Outside that, SFX and music would be good (again, quite an obvious thing).
Cool idea for a puzzle game. Worth spending more development time to polish it and add new features. Well done!
