Sonic Unleashed+

You put much effort in this, great job! You should fix some moments, like:
1. Make the intro skippable
2. Make so that intro is not stretched
3. Remove HUD crop on non 16:9 displays
4. At windmill isle act 4, there is a quick step section. Would be better if player's auto-centred. Without it, you can't allign it at one of 3 parts of track and Sonic will shift.
If you fix this, your project (in terms of quality) will be as good as P-06.

Yeah, this demo is in the rough state. Reminds me of SatBK remake on the same engine in the previous SAGE by someone. But your work is not as bad. I can definitely see the effort but unfortunately either it's my bias against the Dash engine, or it was just hard to play sometimes. Let's get into it:
*This game was NOT friendly to my 5400 rpm HDD. Yes, I understand if the textures take long to load even on medium settings but to not have literal objects loaded? I for a second thought that the loop at Windmill Isle Act 1 was missing, but turns out it didn't load until I dragged the demo to my 500MB/s SSD.
*The camera seems too zoomed in. I get that Unleashed had that but this time it made me feel uncomfortable. Especially in HUBs where the camera was turning quickly with Sonic, making for unpleasant experience for motion sick people (not me though).
*Music between normal state and boost state desynchs.
*If the bobsleigh will stay the way it was programmed, I'd rather just cut it, because it was miserable to control. Either it goes too fast or stops immaturely without the way to speed up.
*Why does it weigh a whopping 13.7 GBs? Considering the size, I expected at least 50% of the stages to be ported but no. This is ridiculously bad compression, especially considering the original weights over 7GBs.
I hope those notes will be useful in the future. What's available is ok, but the demo is far from being considered finished.
