Softlocked myself here because I didn't know double jump was a thing. Started over and finished with 6/7 masks thinking it would be nice to have a timer but felt like I didn't really complete it without having all the masks. So had to do another run then found out the clock itself was a mask and finished with 9:17. I feel like I cheated a little by using the map you posted. Would have been neat to have that map in the game but with unvisited areas blocked out. The sounds were so fitting and gave me flashbacks to my SuperMetroid experience. Fantastic entry. Very well done.

Glad you enjoyed game and I appreciate you sticking through it :)
I agree with you on the in-game map. That was an important feature that I unfortunately didn't have time to add in. I figured it would be challenging without a map so I included a picture of it on the page in case people got lost or frustrated.
Your picture shows the patch of wall on the right that in hindsight I could have put 2 spikes on to make it not possible to pass without double jump and get soft-locked. Play testing definitely help make these things clearer. I think it's also clear from comments that the 7th mask is not easy to find so I would try to make it more visible to the player as they pass through in a post-jam update of the game.
Thanks again for the feedback!
