I really like how you gain new cards with unique abilities, and each checkpoint gives you an area that would be ideal to utilize the item on. The animations are almost too smooth, and the map is very cool. I did let out a bit of a laugh at my immediate death upon opening the game with no abilities yet, but obviously, that was intentional. The only criticism I would give is that I think there shouldn't be as much of a limit on how many times you can use each attack. I often ran out of attacks far before every enemy was dead, even when I'd conserve my aoe's for super compact crowds.
This was a super fun game, though, and I'd love to see more from you in the future! Amazing work! <3
