For 1, Sonic and the crew moves WAY too fast when compared to the camera zoom and the space you can move in. You literally will touch the control stick and your characters go flying off the ♥♥♥♥ edge. I can't imagine that being the problem of the PS2, it's not like the controls magically go bad when transferring from one console to another? But it's not like jumping is any better either, as you have no shadow under yourself and no depth perception, so sections like the lava filling portion of Power Plant are made infuriating (now this might be a PS2 version problem). The camera is another problem, try to twist it and the camera zooms in way too close to even operate. Bugs have been frequent, but especially so in Seaside Hill and Casino levels. I need to mention the 'automated' ramps problem again, but in Ocean Palace, it's infuriating when you go through 6 minutes of level, just to lose all your rings and die, effectively killing your A rank. In casino levels ,the infamous camera strikes again where I sometimes could not land where I wanted to because camera just gave up. But aside from that, the flipper things not bouncing me up, somehow jumping on top of the pinball machine and other problems. But by far, the worst offender so far in the game was level design. The first two stages were actually pretty atmospheric, and it was cool discovering all the secret paths and such. I liked that.
But then we get to ♥♥♥♥ casino levels. I spent NEARLY AN HOUR on the first level. Why? The ♥♥♥♥ pinball machine. Not only was it hard to bounce yourself up, but also atrocious controls which I cannot even begin to describe, the flippers not working when I'm at the ♥♥♥♥ TOP AND JUST ABOUT TO LEAVE, glitches mentioned previously, the fact that you have lots of other ♥♥♥♥ bouncing you around and the fact that you do it NOT ONLY ONCE, BUT MULTIPLE ♥♥♥♥ TIMES, THIS IS THE PINNACLE OF ♥♥♥♥ LEVEL DESIGN OF THAT WORLD LADIES AND GENTELMEN! The Bingo thing was a bit better, only because most of the Pinball machines are optional and the final 'obstacle' is not deadly if you use only 1 character to go down the bingo. Also yes, the ♥♥♥♥ deadly traps at the end of stage 2 of each world. You have to collect Chaos Emeralds by collecting keys in a level, but if you die/get hit you lose it and have to get it again. The problem is that at the end of the stage you get a section which is just ridiculous and you will most likely die/get hit. In Seaside hill it was the rolling rock (and the loopdeloop glitch), in Metropolis it was the Power Plant with no depth perception and, once again weird glitches when attacking the enemies (the only upside this gets is that the key is easy to get if you die). The bingo portion was much easier, since I found out that you can only send 1 character at a time and not really die (that and the key was easy to get if you did die), but still, the camera also was glitchy as hell, the atrocious controls while rolling did not help and the ♥♥♥♥ death traps. Not to mention the Special stages which are stupidly hard with an analogue stick and the fact that Sonic runs up onto the ceiling for no reason on turns and randomly trips and falls -.-
Not to mention that switching is silly. It would most of the time skip the character I wanted to use. I think I know why that's happening, but it could be easily fixed. Going through levels is made more annoying because of this.
