Very good and very fun mod, it very much feels like an upgraded version of metal sonic and it feels very true to the boss, but as always I do have a few complaints. Accidentally beginning to charge a laser is way too easy, I wish it either forced me to press it twice rather than hold the jump button, or that the dash as on jump instead of the laser. (maybe an option to switch the two?) On the subject of charging, there doesn't seem to be much benefit to fully charging either move. A suggestion would be perhaps having the laser either fire 3, or fire the vertical line/ horizontal line/ have both combined into a cross, and maybe having the dash bounce off walls during the initial startup of the boost when at full charge. As for less meaningful complaints it would be nice to have the old metal sonic race theme as an option, (the one that starts with the weird drum-ish riff) having a console command to change the color of his after images, (so they aren't always orange) and perhaps giving him a slightly different goalpost and character sprite to tell him apart from normal metal sonic. However even with these complaints, this mod is still fun and I would absolutely recommend a download. Most fun I've had playing metal sonic in a while.
