can i play this with a controller? if i can, what kind.
You can!
I'm not sure which controllers pico8 supports out of the box, but I've been using an Xbox One gamepad and I imagine a 360 gamepad would almost certainly work too. Other common controllers are probably supported but I can't say for sure.
can u play this with ps4 controller because thats all i have if not i will just play with mouse and keyboard.
No idea sorry - I don't have one to test with. Maybe!
ok i can try then.
