I tried the complete version you shared. The mechanic of mixing a board game with cards seems very interesting. I think you should do more versions following this concept! Since as you said it's your first jam, I'll try to give you some advice: first, there's a general problem with understanding the rules. Icons on boxes are well done, but without written instructions, it's hard to remember each effect. By just adding an instruction section to your game I think you can improve it a lot. Also a phrase like "player one, it's your turn" can be helpful. For the visual, I think you can try to work with pixel art if you want to create something from scratch and simple to make. You can find many easy tutorials on how to make it. Btw, keep working and good luck with your future games! :D
