Have to say, this is one of the finest game I have seen from the batches of Unity games entering this jam.
The game is quite hard, sure, but not impossible. In fact, it’s pretty enjoyable actually from my view.
The game also requires you to consciously paying attention to both money and your HP, which I think makes the game a bit more challenging yet still keeping it fun.
Overall, a decent game. Not the best game out there, but better than most.
