Hey, thanks for the feedback!
I agree. The input scheme did not help the game at all. That's what I get for going too retro xD. I've recently updated the project version to use mouse input instead with a more traditional stealth FPS control scheme. So I'll be posting that once the Jam rating period is over.
You may be able to teleport past the keys, but you're still going to need a copy of the key when you escape. Meaning your satisfaction was only meant to be temporary. xD
Thanks again for playing!
