This is an Absolutely Amazing, well designed character mod.
1 - First, the way you managed balancing an "overpowered moveset" like this is REALLY impressive on its own. Having to learn and master the moveset, AND ACTUALLY TAKING SKILL! Great character design on that point alone.
2 - The Artwork Looks great and is charming, And is pared well with all the visual effects. mixing sonic and dragon ball works amazingly.
3 - adding a custom menu helps a ton. Customization is a genius move, and makes it more personal, which can really help players feel more comfortable with the controls and/or make there SMS look cooler depending on their tastes.
4 - The only downside for me is that the amount of moves makes it feel a little crowded. And can be a little tricky on controller some times. But doesn't ruin the experience much.
But overall really, REALLY well put together, and makes you feel like your playing as, THEE, sonic the hedgehog.
Giveaway name aside, he's widely known for being THE fastest most intense SRB2 character, with every GIF and trailer showing as such. How did NONE of this serve as adequate warning?
And since you found this so problematic, how did you not ONCE try to look into the options to turn down effects or try to turn off screenshakes? If your eyes seriously hurt for a solid 20 minutes, you need to be honest with yourself and take your health issues seriously. There's no world where you're "not photosensitive at all"
