Hi Hatoge! I'm mindblown by the game, so far I've played is amazing!
I think I encountered a bug though... if you go up the stairs two times but then go back one time and go back up the staircase become endless (you can only go up or down the stairs but you always get redirected on this map). I tried a new save file, went only up this time and it didn't trigger, so it must be that specific combination of actions that messed something in the staircase. Basically if you do this: up - up - down - up on the stairs they loop forever.
It also happens if you're on top floor (where the entrance code is requested) and you go down once but then go back up, the stairs will loop again.
You either have to go down - down - down or up - up - up, the other combinations softlock you ><
I hope it helps, if I find any other I'll report!
Btw I LOVE the decoding stuff in the game!
The binary codes are very clever too!
I finished the game and IT'S - SO - GOOD!!!
I wanted to rate it for the jam but it won't let me, so I have to wait for it to finish to do it ;w; but really Hatoge, you reach new heights every game you make and this one is impressive! (The stair glitch doesn't ruin the experience, don't worry too much about it for now)
