I like the idea (I like seeing how different people take the same idea I had in very unique directions), but I think it could use a bit more polish. As others have said, the hero's health is too high, and there isn't much feedback for when the hero takes damage
I think more variety in minion types to allow for some more strategies would also improve the game
Overall, I think it is pretty good for being made in 48 hours, and could be made way better with some more time put into it.
