I'm going to be honest, this needs a lot of work. I didn't even beat the level because I was repeatedly falling into pits due to bad controls or bad camera angles.
The camera was a real struggle. If you're going up a loop, but don't make it and fall... it's hell to get the camera to turn back around so you can see where you're going.
The level layout was probably the worst part. There's way too many traps that you can't even see coming and Sonic falls to his death. It's also very easy, especially with the previously mentioned camera to get lost. There's also many areas where Sonic flies off of something due to a boost pad and can't make the jump, I guess cause he isn't going fast enough? Well I didn't want to go fast cause every time I sped up I died.
The hud looks pretty cool and I like the new enemies. That's kind of a rare thing in 3D Sonic fan games, but there's a lot that needs to be worked on IMO.
