The way the powerups are place in the room made me always go for the one on the left as I just kept walking to the right to reach the exit. I only figured out you're supposed to stop and pick one of them on my third run lol.
I suggest lining the powerups from top to bottom instead of left to right, to give the player a hint about them being exclusive from each other. Maybe including an additional text message as guidance would help too. Don't assume all players understand how roguelike powerups work.
Good job.
