Not a fan of the ESDF movement scheme; always been used to WASD movement. Aside from that small gripe, it's a fun little game.
Honestly, if I could change the ESDF movement scheme, I would 1000% do it. Unfortunately, it's part of PICO-8's weird unchangeable quirks, I'm sorry ¯\_(ツ)_/¯ Glad you enjoyed the game!
It's okay. I'll use the arrow keys and X to shoot.
