Awesome, I'm glad you enjoyed it! I wanted to create a 5-minute experience. If you speedrun you can beat it in under 2.
I've had similar feedback on the knife but I'm glad you figured it out, animation isn't my strong suit. The game was originally intended for VR so it wasn't a consideration. Dodging isn't so useful right now, but it'll come in handy with larger or ranged enemies.
Yeah, consensus is that doors are too confusing. Something to work on.
