Is the whole gameplay idea based on the economy yours? Because it's fucking fantastic. This is very damn promising, i highly incourage you to actually turn it into a full-blown game with more features/levels and possibly PvP and deckbuilding, it's up to you.
It does have one fatal flaw tho: the randomness. Haveing compleatly randomized cards without any idea on what you're gonna draw it's problematic and makes planning very weird sometimes.
If i had to suggest a solution i would tell you to either just make the hand size bigger (i know that it's just 1 for the jam but outside of the jam it doesn't have to be) or alternatively to have the ability to know what cards are left in your deck
I hope to be able to play a full version of this game in the future :D
Thanks alot! The original idea was for it to be a deck building game actually. I do want to work on it more over time, and it has some problems to fix (the Randomness being a big one) another solution that comes to mind it having the next enemy be told to the player. While I probably won't do PvP I do have some plans to work on the game more. Thanks again for playing
