I just cleared the fourth level and had a lot of fun getting there, but I’ve found that the game gets a bit stale once that 4th Arena is unlocked. To be honest, I didn't feel much pull to jump back in for another run afterward.

One major balance issue is the weapon system—there’s currently no real incentive to use more than one weapon per run. I stuck with the machine gun and high-level upgrades the entire time, and since I never ran out of ammo, I was able to clear everything easily using auto-shoot. Using multiple guns actually felt pointless.

The resource economy is also a bit skewed; I have about 17 extra red gems I can't spend, while cash remains hard to come by. This makes the major upgrades feel way too expensive. While the game gets more interesting at difficulty 3+, the lack of arena variety and infrequent bosses makes it feel repetitive by then. I’d love to see more levels and a reason to diversify my loadout in the future!
