I can see this being developed into a well-made, high octane shooter someday! Though limited to being a local/same screen multiplayer, I see potential in this being faster pace and the same kind of hectic as Hotline Miami, which does have cooperative multiplayer, but it would be interesting to see as a competitive PvP. The shooting being limited to the directional keys and diagonal does make certain shots difficult to hit but I will chalk that up to hardware limitations. You have a great thing going here, well done!
