Love the idea of your health, stamina, and currency being the same pool. Definitely got me killed when I got greedy for a charged attack, so it got me thinking about my power management for the next games.
Saw the enemy health bars show how much damage they take from a charged move so that helped plan out some hit and run tactics in the later levels.
Had a few runs where I got some lucky upgrades that had some impact.
I enjoyed the mechanics, look, and sound. It's a fun little game.
