The source code for my game Beach Palooz

A simple surfing game made for the 2017 Global Game Jam. The main character's sprite was taken from Spriter Pro's assets, and therefore I'm not certain if I'm allowed to upload it here so I may have to change this in the future. This game and the assets were also uploaded here: https://globalgamejam.org/2017/games/riding-waves The mouse controls the level of the waves while the player can jump and lean back and forth to avoid falling over and accumulate points. There are also some different/weird/dumb artstyle options.
I made this during my first game jam when I was a freshman. I was working alone and I was not very experienced and it shows. It was also uploaded compiled here: https://vegas242.itch.io/dont-try-this-at-home It's a top down game where you move with wasd or the arrow keys, throw wrenches with left mouse click and drop bombs with right mouse click. There are enemies that teleport all over the place because I only halfway understood how pathing worked. The sprites and animations were used from Spriter, which I'm actually not certain if I'm allowed to upload those, so I started to remake them, but I realized I don't have time right now and I don't think BrashMonkey will care that much.
