Your idea sounds cool! It’s remarkable how you manage to get art and functionality for so many cool upgrades. There’s so much content for such a short time. Some things, though:
The starting range you have with your melee is short, and it feels like I’m tickling the starting enemies, and it is way off the balance curve. Too frustrating in the beginning, making it not very enjoyable to play. Next time, think, is a new player going to enjoy this difficulty, or is it just because I played it so much, it became easy? Also, the music is too peaceful of a start; it should have gone straight into the actiony version.
Other than that, really well done for the game!
