Thanks for review!
About colors of doors - they cycling, so you can explore which color which door have.
But i should've make regeneration of bar faster, so you wouldn't wait so long when it refills, did not thought about it before submitting game :(
And about death, acid is damaging, yeah, should've make checkpoint there, so it wouldn't be so frustration to start again. By the end of the jam i was too tired of making system that i will be able to expand in future development and didn't polish this moment :\
Will do better next jam and future development of this game.
