cute little game, i really enjoyed the experience, specially the ending, it was very sweet hehe.
Now, i think the levels could do a little bit more, like... you can also move left, a level could be only moving left, and others would need to move both ways.
Also i liked the idea of having limited rewinds, and I was thinking that they could be also a pickup in some levels hmmm...
Need to add soundeffects and a bit of music that's all.
Congratulations for making this game, if you update it... let me know :)
