Great game - perfect length, good upgrade path. I like that you don't need to max out upgrades to complete game. I agree that pathfinding leaves a little to be desired, and a magnet upgrade would be helpful, but I don't find that these really detract from the game too much. Keep up the good work devs - I look forward to the sequel!
Wow - not 30 seconds into the game and I get stuck travelling between bubble spheres - I just keep travelling into infinity - nice bug for the very beginning
