Thank you! Although I'm not a full-time game developer, I have several years of experience in game development, mostly coding games from scratch without using game engines. During this Jam, I spent an average of 5 hours per day on this game and wrote about 1500 lines of code in total. Most of the common systems, such as the GUI system and particle effects system, are included in my game framework EON and were written before the Jam started.
