Very nice ideas!
Hello!
I loved the concept and the retro-yet-modern graphics, but I didn't like the font you used for the title in the preloader >_< D00d! It's the ugliest font ever! (especially the "R" and the "S")
Oh! and there's a bug to correct: I kept my move keys pressed while dying and I re-crashed right after respawning. Perhaps it could be nice to have a "Boooo! you died" message before the respawn.
Of course, those are minor details and in overall, it's a very nice game!
