Welcome! Use the arrow keys move. I will probably use this for a story platformer one day in the future... Ok, update, I only shared this because I need the code for a new platformer on my alt, @MrDuffyDo for a new game. I am perfectly aware this game is massively glitched.
Thank you, Lumena-tan for Splatoon 2-Spicy Calamari Inkantation 8-Bit Remix.
