Hoooly... this game is dope. Great job! Following, can't wait to see more from you!
If I had one criticism, I would say it would be nice to have a little more feedback on grabbing XP orbs. As it stands they just kind of go into you and disappear. It would be sick if the screen subtly flashed blue and your character got like a little sparkle.
Just a nitpick, though. Other than that, flawless experience. You really nailed the pacing. Early game you feel like a god, then the slow trickle of weapon upgrades (the players bullet visuals getting crazier and crazier was a great choice) and the allure of seeing what weapons/bosses I'd see next kept me going. Then before you know it, the game is hard as hell and I reach a "zen" state of focus.
Sorry for gushing, I just don't see many games like this on Itch. Dope game.
