Really cool idea and the music was a really good choise imo and added to the pacing of rushing through the levels :D
i liked the dash ability the most and also just dropping dead and the music stopping was really fitting and then restarting again. everything felt good. autojump was cool to bounce around :D (keeping jump pressed)
The character reminded me a bit of kirby (the gameboy/nes version) dunno why and i was hoping for a little kirby dance in the end lol (im just kidding, but it would have been epic :D ). the artwork was really cool. great game good job :D
