I really enjoyed this entry! The masking effect was a nice touch. I had a little trouble with taking multiple damage hits from enemies (especially the big bosses) - maybe a brief period of invulnerability between taking damage? And I wasn't able to enter the room with the big skull with the two little skulls flanking him - I saw the boss and backtracked, but then could not get past the constant projectiles to get back into the room. Perhaps they could de-aggro if you wander far enough, or prevent the projectiles from going through the wall? I didn't quite finish it, but enjoyed what I played and will probably go back and try again after the jam rating period is over (trying to rate as many as I can in the meantime.) Beautiful art (and nice subtle effects, like the snow falling off the plants as you jostled past them) and a very cool entry. No pun intended!
