I really enjoyed the backwards play style. I did want more of the game though. I'd definitely add more levels as I can see this being really fun. Sorry to hear about deleting the itch game file, bummer.
Also potential to allow the player to jump when time is going forwards as well, to increase the odds of death/fun. I'd add a 'died' or 'you win' too . The art is beautiful and I did chuckle out loud at his dancing.
