Obviously it's a worse version of X and X2 but it works well enough. Absolutely need to fiddle to get the start=dash keybind to be on a more sensible button. Music is worse but they did a good job somewhat of keeping the feel of the stages. Most of the upgrades are still here and the collectibles too. Bit annoying that you gotta go through sigma stages twice for no reason if you want to see it all but whatever. I still couldn't get the hang of the auto wall dashjump since I was too used to manually doing it.
