I played the new level 3. Very hard, but beatable. I’m not sure if I could have done it without leveling up midway through though. You need to remove bad guys who are directly next to the door, because there is no way to avoid losing at least 30 to 50 life in that situation. Sometimes you’re completely surrounded and can’t move, losing up to 100 health. Just one enemy near the door is fine, but 3 is pretty annoying and just makes you lose life no matter how good you may be.
Also, the AK is a reasonable weapon after one upgrade, so I think it’s okay at its current level. One thing you should probably do though is allow you to holster your extra weapons somewhere near the weapon shop so you can swap out weapon choices depending upon the situation. I want a shot gun, but I think in terms of all purpose a pistol and an upgraded AK are better, but I would like the option at least without eliminating my old weapon. This seems especially necessary now that you allow weapon upgrades.
Looking great, though - it’s certainly fun already!
