I just realised that nowhere in the rules it’s specified that your game needs to be an .exe file, so your game technically is totally within the rules and valid!
However, I don’t own the TI-series calculator – they don’t sell those in my country – and I had to download an emulator. At first it was quite frustrating because I was using WabbitEmu, which I don’t think supports the calculator version for this game, but I thought it was a problem with the config, and CEmu didn’t work with the ROMs Wabbit made, but when I finally found a proper ROM for the TI-84 Plus CE then it was easy to run the game in CEmu.
IDK what I was expecting but it turned out just to be a regular snake game XD, but if it weren’t by this, I would have never known there existed a community making software for these calculators, something very nerdy and niche, yes, but for me that’s also like the coolest thing ever lol
