well this was cute! I was a little confused as to what I was doing, besides running to the right. I seemed to be able to "get" the blocks that were my color, then later interact with the heart blocks? a little explanation possibly could've helped. The music was nice, and the little faces were adorable. :)
edit: oh forgot to mention, it appears this was made in gamemaker 1? The rules say it has to be made in 2.... :/
