Hey there! Thanks for the review and feedback. Let me see if I can help improve your experience based on what you pointed out!

- In general, this is a Arcade genre shooter where all improvements to your character are through immediate powerups you pick up from killing enemies. The 'How to Play' shows what each powerup provides the player.
- Once you defeat enemies, they can drop Powerups that include Health regeneration that heals your character. They drop frequently and will keep you alive.
- Your characters playstyle can change based on the projectile powerup you pick up, Fire, Ice, or Poison. You also can get a rare drop of a attack shield which makes you immune to damage AND you can charge into enemies, quickly killing them.
- As far as the hitboxes, I made them pretty forgiving for each enemy. There is a visual and audio identifier to let you know you hit the enemy. A visual smoke effect and a retro thud sound should be what you experience. Some enemies have more health and require more effort to bring down.

Based on the High Scores of other players, I would encourage you to keep playing and experience the maps and bosses further into the game. Once you get a hang of the playstyle, you can surely best the top score!

Feel free to reach out to me on the Community section of this game's store page here on Steam, as I left a Feedback section for players. It would help me out in making a better experience for you and other players!
