Eh, I'm not bothered by it. Difficulty in Sonic games very rarely seems to be something that can be well done, due to the whole ring system. The only way to make Sonic games really challenging is by including cheap things like an overabundance of bottomless pits or cheap enemy placement that you have no possible way of countering without explicitly knowing where the enemy is beforehand, and that honestly just feels cheap instead of actual difficulty and comes off as frustrating. Either a Sonic games is too easy, or it becomes too cheap and frustrating. If I want a difficult game, I'll go back to playing Castlevania 3 for the 100th or so time, which despite its flaws feels incredibly rewarding for getting past it's difficult sections. I play Sonic games for reasons outside of being difficult (Music, level design, aesthetics, controls, physics, etc.). For a Sonic game to be difficult without being cheap, I honestly think the ring mechanic would have to be scrapped in favor of a health system or something along those lines. In the old games, if you get hit, you have plenty of invincibility frames to go back and grab a few rings as well as taking out any nearby bosses/enemies without regard for Sonic's safety. Essentially, if you're a smart player then Sonic has virtually unlimited health unless he falls into a pit or something.
