I'm surprised this game's rating isn't closer to 5. It has a wide variation of well-crafted puzzles based on simple rules that create a deep and challenging (NP-complete) mechanic. I thought it was great.
In addition to adding a speed up button and a tool to draw strait lines, I would like to make the game more interesting by having the cup explode if you put a single grain of the wrong color in it.
I don't like it that you can win or lose based on how long you have to wait for the balls to bounce. Allowing the player to return focus back to the ship on mouse click would be nice.
Need to have a special clickey sound when you've just squeezed out your last bullet, so you know to change weapons if you can't afford to wait for a reload.
Just figured out that the numbers turn gray when your selections are *correct*, not when you've just filled a number's slot up. This makes all the otherwise decently difficult puzzles trivial. Boo.
Grammar errors make a game look bad. Unless you're Japanese. Then you can get away with it. I see so many now, good games that get ruined with basic mistakes because the authors are not native English speakers. Maybe Kong should offer a service to proofread for a small fee.
