loving this thing so far but the room with the vaccuum spider runs at 40 fps while everywhere else so far is at 60 turned off a couple things in menu but it didnt help is there any way to fix this?

almost exactly. I checked. Anyone else got this problem? I can't figure out what it might be. On that note, two things that would be nice: 1) starting at the last checkpoint when I re-open the game, instead of at the beginning. 2) being able to use the map properly with a controller....

below the room 'origin' I can't kill or something to that boss I got 28alloy right now and i got every alloy in every room(as far as i know) but I can't progress to any room but 'lair' or 'final frontier' I've tried to place orange bomb to that wheel but it didn't work or do i have to get rid of every wall that breaks in that room? Does anyone know how to kill that boss? (plus, how do i get to strange room...?)...

At the second phase, the boss always kills me with one hit. No matter I run cricle or stay still, the bullets of the boss is so fast that I can not dodge. I have worked on this for an hour, seems it is too hard for me, so please tell me how to do it. And I got 41/42 alloys, will the last one come out after I defeat the boss? Cuz I have searched all the rooms. Nice game, enjoyed it so far....

Will itch.io purchasers receive a Steam code?
