the game wasn't enjoyable to play much, the mechanic felt kinda... not very interesting. i don't think this was a very good idea. it's a little complicated and just... outright not fun. however please don't be discouraged by this. everyone gets not the best ideas sometimes and i'm sure you'll come up with something much more fun and everyone struggles with coming up with fun mechanics, so please keep on trying and i'm sure you'll eventually end on a very enjoyable game mechanic
i will also say that the game feels very empty without any sound design, so that's something to take into account for next time.
as for good things i can say about the game: gosh it looks very pretty. how did you create a lighting effect like that in 2d?! please teach me!
