When I initially saw the screenshots I wasn't too sure about the game, but this was actually really well done! I love upgrading my dice, very Dice Forge-like. It was actually a difficult game too! I definitely lost lol.
The only improvement I would suggest is that the firework sound effect felt like it went a bit too long (a screen or two too far). Beyond that, this game was perfect and just ready for expansion!
Overall, I really enjoyed the game and am actually going to give it another go after I post this comment! Nice job!
