which engine you use BTW The games was beautiful i like mixture of pixelart and 3d it was giving a cool effect
it also remind me of megaman.
5 star
Unity, although I wouldn't say that it has a great support for this kind of artstyle.
I recently saw miziziziz making a game with ps1 style graphics in godot.
I don't know anything about gamedev but maybe you would like godot?
