Thanks for all the suggestions! :) I think JKL (or similar keys) would be good keys to use since the attack and pickup buttons could be close together without accidentally triggering Sticky Keys with shift. Space for jump could potentially free up the up arrow key to allow the player to pan the camera up to check the upper area of the stage without having to physically go there. Vertical and/or air attacks are things we’d like to add to help deal with pesky flying enemies!
Yeah sticky keys are always annoying, I played it again and I must say that while only using the arrow keys for movement, the space bar attack makes perfect sense and feels right. I was just a bit confused since I have a preference for awsd movement. I'm looking forward to seeing where this project goes in the future, and best of luck to you guys with the jam results!
