Wow, that's a really clever concept! I'd love to play a version with (more robust) enemy pathfinding and different/remappable keybinds (z and x were hard for me to use while wasd'ing :p switching via scrollwheel might be interesting?)
i thought about using scroll wheel, not sure why i didn't. wouldn't be hard to implement either, so if i possibly finish this game one day, that will definitely be an option!
keybinds are a whole other thing, that i don't know how to do yet lol
