Most of the comments say "too hard"... Well, duh, indeed. After I came back from my holidays I wasn't able to play my own game anymore! Too friggin' hard, indeed, probably too many things to control at the same time (the grabber, the rotation/control, speed)... Here's a list of what players offered me to add to make it a bit easier:
- Levels of difficulty. Say in "Easy" you just grab the boxes by passing over them, this removes a fair deal of complication. In "Normal" you use the grabber.
- Rotation speed limit -- other system for rotation. The main problem with the UFO is that it can rotate too fast, there is a need for an upper limit. Alternatively the rotation could be made non-perpetual, ie the ship would go back to a rotational stop after the thruster is turned off.
- Launch the ship in the arena directly in orbit, instead of a fixed position. I think this is good advice.
- Oh yeah, and removing the "power bar" of the cannon and having it fire at maximal power all the time.
I also remarked a few problems with the "multistar" mode, that have to be worked out somehow (the ship isn't powerful enough to perform when several stars are present on the screen).
Well, I guess it's far from finished yet... Thanks all for trying this out :).
