Kick ass homage
That was a lot of fun! Felt almost like a sequel to Pico itself. I think you have the spirit of the game down pat.
I can think of only three things to bring up otherwise.
1. Add maybe a lil more background music.
2. The level lay out was a little too linear.
3. I like the ending you went with more than the alternate.
3.5 I hope to see more! :D
