actually you can't change those buttons, I've tried and it won't let me. I don't have this problem on the web version. The only one that works is by pressing 9 for the debug skills cheat.
Ah my bad. I've indeed implemented reconfigurable controls for the debug keys, but only on the most recent versions on patreon. This free version here on itch is an outdated version where the debug controls are unfortunately fixed like that.
