Eh. It's pretty nice, I guess. The idea is pretty neat, but it could be done a little better. For one thing, sometimes there wasn't any bubbles of the current color, so all I could do was wait. And waiting isn't very fun... And sometimes, the bubbles were too close together, so I couldn't get the bubble I wanted in the middle without getting hurt. :( The music is great! I've heard similar music from Skellus' Linx games. Actually, can I ask what program you used to compose the music?! I've been wondering... Anyway, the music is great. The sound effects are... well, the gameplay sounds are literally ripped straight from Minecraft. I admit, they fit pretty well. And the gameover sound effect is... a generic cartoon "wah-wah" thing, so that's pretty bleh. Overall, this game is okay, but could be alot better. 2/5 stars...
(PS: When I switched back to this tab (I'm on the game over screen), the very end of the game over sound effect played. Weird...)
