First of all, that opening gave me Spelunky vibes, which is definitely a good thing. The whole game was just so well polished, like you'd had months on it. So, incredible work to your artists. The gameplay was also great, with a lovely dice mechanic that burns out, forcing you to use new weapons. It would be great to see a bit more variety in these, if you're planning an expanded version, but what you had was great!
Wonderful work!
