I originally had another level inbetween levels 1 and 2 that introduces the green blocks but my friends who playtested said that level wasn't as strong so I left it out, but green blocks just end your invincibility! So the part I'm guessing you might be stuck at is where the floor is glass, and you need to dash through the floor to proceed. Definitely wanted to add more polish and instructions to make all that more clear but just ran out of time!

Aw darn! Yeah that's not supposed to happen, sorry it's not working right on your end, thanks for giving it another shot!
