Crash 4 is getting brutal and as much as I love the game, I don't think I'll 106%. They really embraced the whole "hiding crates offscreen" aspect, it's much more common in this game than the original trilogy combined, it feels like. Also I wish there was an easier way to do the whole perfect run challenges. Right now when you die, you have to completely restart the level from the pause menu, which for some reason has to load the level again, resulting in a huge time sink. Especially weird because that's not an issue with time trials and restarting from checkpoints. You'd think with the level already loaded, you could just quickly restart. Seems like a weird oversight to me. Another small issue I have are the grinding section. They are fine enough, but sometimes I simply have trouble seeing what's ahead. Maybe it's the level design, camera work or a mix of both. But then again, I am kinda bad with depth perception to begin with.
And lastly, screw Polar. His hitbox just feels off (I swear, I phased through crates more than once) and his controls also much more floaty than the riding stages in past games. Oftentimes it just feel like I'm barely in control.
I really like Tawna, Dingodile and Cortex though, they're fun to use. Same with the new masks, though sometimes I forget Aku-Aku exists, He doesn't appear often, neither in stages nor cutscenes, which is a shame. Seeing Oxide and his hovercraft was a nice surprise as well, I wasn't expecting that.
