What you see is what you get, after all.
One of the most comfy and overall fun experiences I've had with this game. He controls ludicrously well on both controller AND Keyboard & mouse, and his moveset flows together super nicely.
Spindash is certainly a strong tool, what with it's insane speed conversion and overall control, but I'd be a fool to say it's what he's all about. The technique of uncurling in the air to momentarily negate air drag has been a bit more useful than one might think it'd be, and despite it seeming to be practically useless I've found a pleasant amount of ways to use the spindash hover technique to my advantage.
Homing attack is quick and snappy as it is in Adventure 2, and homing poses make it all the more aesthetically pleasing. Far thok serves as a VERY nice middle ground between single jumps and the homing attack, letting you have the burst option without forcing you to risk homing in towards an enemy if you don't want to.
Bounce attack is super versatile here, from helping you get just a teensy bit more height when you need it, or helping you platform slightly more precisely, or even letting you perform a superbounce with speed shoes/super (you can also use the bounce to "extend" homing chains to keep the poses going, which is a small thing that gives SA-Sonic a teensy bit more flair in my book.)
The Lightspeed Dash/Lightspeed Attack, despite being moreso based upon Adventure 1, functions wonderfully within the scenarios it's meant for. Want to grab a cluster of rings or fly across a line of them? Light Dash. Have a group of enemies you wanna take care of quickly or have an enemy you really don't feel like dealing with? Lightspeed Attack and watch it get turned into scrap. The Maximum Heat variant of the LSA that goes for enemies only also eliminates basically any issues of going for rings you didn't want in that scenario.
While his custom physics took a bit to get used to, they allow for movement and control that's significantly more precise compared to that of Vanilla SRB2, and it makes playing him efficiently feel way more rewarding and satisfactory.
On top of how he plays, all of the sprites and visual effects present here are absolutely gorgeous. I have yet to get sick of seeing any of them even a little.
It's been a long while since I've had a character that holds no notable complaints from me, and SA-Sonic smashes through this threshold with flying colors. Happy I was able to help in ways that I did for such an awesome project filled with very commendable amounts of passion, love, and effort.
All 7 emeralds collected more times than I can count at this point. Go play him. Gotta open your heart, dude.
