I made most of the code for offline mode. Just need to add attacks and HP. Choose 2 characters, the first one will be P1 and the second one will be P2. Then click z to select a stage, press start and you will be teleported to the arena. P1 controls are arrow keys. P2 is ad for moving left/right, w to jump, and s to shield.
(This game is not done yet, and online mode dosn't even work yet. So don't have too high of expectations.) All art made by me. And I'll put who made the code once I actually make the code. Tell me if anyone knows how to make the code for an "Online Multiplayer". Worst case scenario, I can just make this only an Offline Multiplayer.
