Did you already make a new game, or is this just Solenoid with a different name?
Anyway, for a game with "Hyper" in the name, it's fairly slow. That may just be a frame-rate issue. I don't know.
In any case, I felt like I didn't have enough control. If I was ever bounced toward an open space, I had absolutely no chance of saving myself because the left/right movement wasn't fast enough. Unavoidable deaths make this game, which could be fairly enjoyable, a bit annoying to play...at least, for me. It's got potential, though.
The only other thing I noticed was that sometimes I didn't pick up the jewels or whatever they are when I killed enemies. It would be nice if they were picked up automatically.
Hyper Solenoid is the same game with several changes in control, speed and objectives, always beign highscore with some twists.
The reason why i made a new solenoid with hyper prefix is that i liked solenoid classic and just wanted to be like that.
I cant tell if you have a framerate issue. Collisions skipping sprites sounds like a several framerate issue as you tell me that sometimes you cant grab a gem even touching it.
Its too bad for me that you cant experience the game as it is, whether its good or not and i hope you can describe where do you see its potential, its very important to me since im trying to improve, Solenoid is my fourth game so i dont expect to be good, just learning.
