Interesting, the author is recompiling the Xbox game to PC, and complaining about the poor graphics of the final version.

IMO the gameplay and glitches are a significantly bigger problem. One Argentinian decided to take a different approach, rebuilding the game from scratch in Unity despite having no prior programming knowledge. It's called Project 06 (or P-06) and it's almost complete.

Sonic 06 can maybe be fixed at a technical level but not at gameplay level, yeah. Tortured myself by playing it through it twice and when you do know how to handle the game (don't do XY or the game freaks out, avoid jumping here, don't touch the analogue stick here...) a few Sonic parts can be quiet enjoyable but the rest of the game is such a shitshow. I even played ALL of the side quests for Sonic's part and it was one of the worst experiences I've ever had in a videogame. It's interesting to read about the development and people trying to "fix" it though.
