I really enjoyed your game! It’s a fun challenging little game and I appreciate how many upgrades you can do.
I think you have something very fun on your hands, I just have a few improvement suggestions. :)
- You could add a manual reload
- I’d love to be able to see my progress towards the next upgrades
- The player could heal after any upgrades not just the ones to the health
- You could look into adding other enemy + weapons type
