Great game, I enjoyed the role reversal concept, the UI was really nice for showing how long units will take to spawn and there was some nice variety in enemies, the ability to effect the players time to attack was really cool. For improvements I think the player should only be able to heal at the end of the round, its not as satisfying to get the player lower for them to heal and your sat having to wait for the round to end, I think it would help make you feel like you're progressing more, if health being restored needs to happen for balance reasons perhaps enemies could drop potions ever so often? It would also be cool to see whats unique about each enemy with a tooltip when selecting such as spawn time and any other differences there may be so its easier to make judgements as to which card to pick. Great submission overall though
