Really great job guys! One other thing is that money also gets really irrelevant relatively early... one suggestion might be to add permanent upgrades not in the form of cards. Max health upgrade, score multiplier, etc..
Yes I think these are some good ideas. We deliberated on perma updates but couldn't test them enough to add them confidently. In the next iteration though we are likely to have them.
Thats a good decision. Unlike my decision in my game to make the final level scrolling in the last half-day of the jam, I didn't test it enough and it turns out it lags exponentially every time you die
