This is a very addictive game mechanic. I have no idea how many hours I have played "Bubble Trouble" back in the days :D I like the restful color palette you used. A few sound effects would complete the experience. Nice game all in all!
Thanks a lot for playing and the feedback!
Yeah, I planned to add some sound effects but I had some tricky bugs to fix and then there was not enought ime left for sound, sadly.
