You haven't created an export for the Windows version. It looks like you just uploaded the project files. If you open the project in Godot and go to Project menu > Export, you should be able to just click Add... > Windows Desktop, then Export Project to get an .exe and .pck. Zip those up and upload the ZIP and you should be good to go. Let me know if you do, because the game looks cool and I'd love to play it.

No problem. I just downloaded it and it ran with no problems at all. I love the look of the game- the colour palette is really nice and everything is clear and well presented. The controls are clean, responsive and easy to pick up. The SFX are great and the music suits the game well. I almost felt like there was a puzzle element to the game (not sure if that was intentional) in terms of figuring out how to get past the prism, and it felt rewarding what I figured it out. Overall solid effort- nice work.
