ソラ Sora Ver 1.1 - Special Match Mode - All S Rank Clear
88Sora is a very fun doujin game made by Orange Juice which are the same creators of Suguri.
The video will probably make no sense to anyone not familiar with the game but let's just say that you can dash through most bullets and lasers but you can't dash through missiles, explosions, fire and objects.
There is no limit on dashing but dashing increases your heat which in turn makes you take more damage if you get hit. Furthermore, dashing through bullets increases your hyper/bomb gauge.
I also make heavy use of the cancel mechanic. If you press dash immediately after firing a weapon, you cancel it's animation and you can fire again immediately.
There is some trickery going on on Hime. First of all, dashing there in the beginning can net you over a full hyper charge. For the first phase I whittle her first healthbar down to almost nothing and then damage rush her right after her hyper in order to skip the second phase.
Red is dashable, blue is not.
Suguri's final pattern is a complete nightmare as you have dodge while constantly dashing and controlling your dash is not the easiest thing. You can't use the walls as the lasers's splash damage on the walls hurts you.
