I shall follow usual protocol and give you my pros and cons regarding the hack. Hold onto your hats, Ladies and Gentlemen: Pros: Some of your music choices are very nice and I like the use of music I haven't heard before. Shadow's moveset is rather large and gives you plenty of choices. Layouts generally flow well and have minimal dick moments, which is nice to see. The art edits and modifications are quite well done and don't clash. Tweak the palette in a few areas to make them stand out. Ports of Sonic 1 objects work quite well in the levels they were used in. Cons: Loops in Bayside Atoll don't work from a theoretical point of view. If one corner shows you going behind the loop, the other should have you in front of it. Act 1 has loops where you go behind the wall on both sides and Act 2 has you going in front of both. I also managed to fall through one and get stuck underground on the wrong path as I couldn't exit through either of the tunnels. The ramps in Bayside Atoll are very glitchy. Even standing on them causes you to jitter up and down. The camera snaps too quickly during a spindash or peel-out. It was rather jarring. The miniboss of Bayside Atoll has many issues. The background graphics flickered when I entered, there's too many objects all over the place, causing flicker and I got stuck inside him during a jump causing 6 hits at once. Also, it's just the Green Hill Boss with 2 wrecking balls. I actually *sighed* at how depressing it was. The wheel of feet animation starts way too early. It just looks wrong. Getting a shield and invincibility at the same time causes the graphics to swap between them. The bubble bounce doesn't bounce. it just drops you to the floor. I got stuck in the wall just before the boss of Bayside Atoll 2. I had to wait for time over. Royal Ruins has one of the most unfair beginnings to a level ever. I had no and rings jumped into a ghost (expectant behaviour from S3K and died). I tried again, dodged the ghost and got hit by a really fast arrow. Yeah... thanks. That was Game Over as well. Shadow's Chaos Control seems pointless at the moment. You can spam it to get an incredibly low time but apart from visually, I noticed no benefit. I know it's unfinished but I kept triggering it by accident after a combo attack. It's hard to tell the difference between foreground and background in Royal Ruins 1. Too much brown/orange. Shield graphics interfere with the boss hit count. Either behind or in front of it. Royal Ruins 2 has an issues with a red spring next to a 45 degree slope. The spring doesn't work. Again, my apologies for the large list of issues but most of them are minor and can be fixed rather easily. I enjoyed playing it, for what it's worth. I just feel it needs a little polish in some areas.
