This was super neat. Gameplay reminds me a lot of old 3D web games. Felt so satisfying being mid way through a jumping puzzle, scrambling to make it before the solar flare hits you and just making it! I also was very fond of the little sprinkling of humor into the story. I imagine if I lived on Mercury I too would want to partake in taco Tuesday... That being said... Do they even have a Tuesday on Mercury? Huh...
Anyway, awesome job on this man!
