It was interesting and fun while it lasted. I like the quirky utilization of death in this game. It reminds me of SeppuKuties (http://www.newgrounds.com/portal/view/467521), and I think the challenge would have been more substantial had you taken a page from SK and implemented a game-wide consequence for death that forces you to conserve your lives rather than mindlessly mashing through a level with no consequences.
On that note, the game was very short, and way too easy. I beat it in about 10 minutes.
The last level reminded me of something you'd expect to see in I Wanna Be The Guy or VVVVVV, but it was uncharacteristically easy, as I finished that level in 3 tries (2 deaths). The first death was falling into a spike on the right side, and the second was from the platform on the bottom unexpectedly rising. But after those two slip ups, I zoomed through it with little effort.
With that, I think the level design could have been done better. I feel it was limited and lackluster. This game has so much potential, and I see that you plan a possible sequel/extension to the game. I say, go for it. Take this game and run with it to its limits!
For now, I'm hitting "follow" (the heart with a plus in it) and awaiting your next project.
Until then, good luck!
