Wow !
That's a lot of mechanics for a jam game ! Really impressive !
The visuals are amazing, the music fit well & the gameplay is really fun once you get the grasp of it. It even have a shop and & collection/deck management !
it took me a few games to really understand it all but once you get it, it's very well rounded and a lot of fun. The dices were a bit confusing at first, but that's mainly because I didn't really take the time to properly read the manual at first. (maybe making it more visible would push players to open it right away)
if you plan to iterate on that game after the jam, the only thing missing for me right now, is maybe the ability to sell your excess of cards in the shop so you can buy more boosters. [edit] and more levels so I can come back and play more please :p
Amazing work !
