Top down shooter developed in Game Maker Studio v1.4X over the course of about half a year. Worked at the time development stopped, but unclear if it actually works right now. Might need some extra lines of code to handle VRAM properly. Folder structure is NOT properly maintained when uploaded to GitHub, hence the scripts are a MESS.
2022-01-25: Workaround found for earlier problem, it now compiles, but the FX surfaces are not as tidy as they used to be. TBC
The executable EXE requires a gamepad. The control-scheme is... different. Press 'Triangle' / 'Y' / Top button for some help :)
