I loved the intro cinematic! I think the game is solid - I really enjoyed how you slowly introduced new mechanics as the levels progressed. My favorite was the navy blue wall-type with the stacked green baddies behind it!
something a lot of platformer games do is let you jump higher the longer you hold down the jump key - this gives the player a little bit of dynamic control-> tap to hop, hold to do a higher jump.
My only other note is that when jumping between the tall Pink baddies (sometime in the 1800s I think), it would be nice to be able to see them better (and maybe make them wider). it's sort of a leap of faith as implemented.
Thanks for making this game, it has a TON of character.
