I was really loving this game, everything felt great and the difficulty progression from worlds 1 to 3 felt natural and fun, and then from world 4 onwards things got really out of hand in a way that didn't feel fair at all, with the fog that hid bombs just out of view until it was too late, made it hard to judge which shots are and aren't homing in the moment, and is just conceptually a pretty shit mechanic for this kind of game completely ruining the vibe, and while it does go away in the next world the level design really doesn't recover and generally turns into a trial and error slog. Obviously, a game of this nature is going to come down to trial and error at the end of the day, but the level design really goes out of its way to prevent you from having a chance to see anything coming and just makes you bash your head against the wall for ages to make any progress, testing your patience moreso than aim or movement.
These level design issues are made worse by how off-center your gun's shots initially are, making them likely to hit nearby terrain rather than whatever you're aiming at or miss altogether if you're too close, and the tiny little detail that you don't have any crosshair to aim distant shots. To be fair this is fixable with third party software, but it's an inexcusable omission in a modern shooter, let alone one that demands perfect accuracy. idk, this game might not be for me but it was extremely noticeable just how fast it went downhill.
