Neat entry! Also had the idea of customizing dice for combat but didn’t end up running with it.
The system for dice crafting was neat and worked well. It’s interesting that you have not only limited die faces but also limited weight, although at certain points in the game the choices didn’t feel super meaningful (if I’m limited by weight, does it matter if I have a 2 face and a 0 face, or two 1 faces?). This changed up a bit with the elemental damage and higher-capacity dice later on.
I did run into one glitch, where the audio got stuck on some sound effect after the double-jump boss. I had to turn the audio off after that point. But up to there you did a really good job applying the sound effects you found for cinematic effect (although dice rolling and damage sound effects would certainly have been welcome).
The pixel art is simple, but you did a good job filling in the gaps with the text scrolls. There were a couple prompts I missed because I moved through them too fast, though.
I think the biggest room for improvement is probably the more “game feel” parts. The combat tends to be jumping around and kiting enemies while throwing dice; but because the dice wait until they settle before they deal damage, this sometimes means a particularly bouncy die will just miss entirely even with perfect aim. The player movement could probably be a bit faster and less floaty as well. This was a little annoying when having to backtrack after getting powerups, since the combat is generally more interesting than player movement.
Congrats on making this in 48 hours!
