Great, thanks for giving it another go! You're right, it looks like I forgot to actually add a check in the code that you have the doorway powerup, lol. The game is supposed to be a metroidvania, but since my game is so linear up to that point I totally understand that needing to go way back isn't obvious. I was running out of time before the deadline to put more work into the level design, but for this genre especially I wish I had dedicated more time to it.
