cool game, i really enjoyed making things go boom, you nailed the explosion effects. when multiple colors get added to the screen and theres a big chain explosion it looks awesome (plus the screen shake, SFX, etc etc). I think this would make a pretty fun little mobile game just about as is already. maybe adding a sandbox mode where you could just draw and explode stuff would be pretty neat too. i think you made a really well polished game with a good application of the theme. the only minor critique is that the gameplay loop is a bit too simple and gets a bit stale but it is a game jam so kind of an unfair criticism. great entry!!
