Is there any way to change movement to arrow keys? It's simply weird to play with WASD. I tried changing the key binds, but it didn't recognise the arrow keys on my keyboard.

I've beaten the game (absolutely loved it its brilliant), and there's one door listed as door? that seems to be unused for regular playthrough with a long numeric passcode. Has anyone found any leads on how to access this yet?

How hard is the platforming? I do not play platformers often. :(

Sometimes Dan can't shoot to distance, it's blocked in ground or something but if jump bullets go away

Anyone else experiencing frame rate in the low 40's during certain sections of the game. GPU is showing as hardly being taxed and its running off of the internal memory so believe that rules those two potential issues out. Cannot understand why this would struggle as the game in some areas is fine and the graphics arent high res....
