I don't suppose you could fix it so that trampolines don't dissapear until the death line passes over them? getting stuck on the bottom of a screen because they disappeared right before you bounced back up on them sucks quite a lot.
It's a decent game except for the TERRIBLE controls, over half the times when a combo uses z or x it fails to work entirely, and CPUs use them not only flawlessly everytime, but with no actual movement (the commands that activate the combo) beforehand to tip us off. Fix the controls.
Woo, finally got the 60 second doomsurf trophy, managed to go all the way through salty flats and wound up with a 79.4 second surf :D. stats were 4 speed and strength, 5 jump and accel.
It could use some tips for which upgrade to go after first (ALLIED SHIPS) since if you try to go cannon early on you find that the yellow suns regen faster than you can shoot them, and then all the other ones murder your station.
It's a fun game, but the later levels take a while to beat, and level 12 is rediculous (farthest i ever got was 52 out of 60). I would suggest maybe making the circles last just a little longer each level, hopefully countering how you have to have all but a few balls exploded by the final levels.
