Many bugs included indeed. Rapidly pressing fire seems to throw them spikey things into the floor, holding down and the direction keys seem to slide the player around. It's just a really basic platform engine?
thank you for commenting
the engine is still really basic indeed since i haven't figured out how to handle the collisions with the background correctly. and for some strange reason i can't seem to link the screenshot correctly, even though that's the correct image url. if anyone could help on this i'd be most thankful.
