I only play on ps4, if i submitted a run would it count? Sorry if it's a dumb question.

No. Everyone speedruns on the PC version, so you could consider just buying that. Can you even reset the game on PS4?

funny there's not even a platform selected for this game

Yah If you have afterbirth+ on ps4 with all booster packs you can reset by presssing both analogs at the same time
