I like the shield designs, though the fire one might be a bit too fire-y. And in one of those shots the rings are bloom-less.
That test level, from the screenshots anyway, looks pretty good. Wouldn't mind playing this!
Ah diddums. You flooded the forum with vague requests for help and then all but demanded a particular complete engine. Why should people feel inclined to help you after that?
Going to be checking this one out. The Sonic 3/K version of the drowning music, by the way, is startlingly out of place in comparison to the use of the '06 soundtrack, so you may want to use the Adventure version of the track instead?
