It is a horrific port. It physically hurts me to see such an amazing game mangled so horribly.

The game looks worse than on PS2. The game is minimalistic graphically, so the increased resolution doesn't reveal any new detail or make things easier to spot. However, it does reveal the previously hidden extremely low-polygon geometry and shockingly pervasive pop-in, which wasn't improved at all in the transition.

The gameplay during bosses is almost completely ruined. The slightest movement from any boss sends you flailing for several seconds, unable to move as you cling on, waiting for the obnoxious and lengthy animation to end. Attacking feels totally random because you never know when a boss will move and negate your attack as it's charging.

Sometimes, you'll be tossed about for the length of your entire stamina bar without ever getting a chance to attack, forcing you to drop off the boss, recharge and start the whole process over. It takes forever to climb anywhere on any boss because you'll invariably be thrown around five times before reaching your destination. Some bosses have flat surfaces on top of them so you can walk instead of climb, but the physics are broken on such a fundamental level that you trip and fall there too. Time trials are completely random, and some (#3 specifically) don't even seem possible now.

SotC HD doesn't look good even compared to other remastered PS2 games, but for some reason it doesn't run well either. It's 30 FPS with a weird motion blur effect which looks worse than it did on PS2.
