Ok, the controls are different from the original game. press space to turn to a squid and back and use the arrow keys to move you're only supposed to ink when you're moving as a squid but it doesn't work like that because i'm really bad at coding (inspired by another project i saw and also the ink is pen)
Is this even an engine..? Because unlike you I use the arrow keys Logo from google Nintendo for music and splatoon (remade with noteblocks) also it was so loud i even had to go inside the project and lower the volume by 90. you see, my ears aren't as sensitive as your's..
