Of course! If it's for commercial purposes, you need to purchase the paid version tho :P Otherwise, feel free to use it for non-commercial projects!
I came across a bug :( the costumes keep turning into the character costume even when i upload the seed costume
I think it’s not the asset bug, though? I think it’s something directly connected to the engine/code you use!
Yeah I know it happend with 2 different tile sets, I got discouraged after that so i just gave up.
maybe try googling the issue? Or asking on coding forums?
