The imprecision is really irksome on lvl 20. If you have this problem, forget about the score and spam bombs with somewhat varying times, and rerun workable solutions until you achieve victory.
Normally I give games I play a 5 if I can enjoy them for half an hour, but the buggy imprecise nature of this game, that should be precise, makes it frustrating.
This is a buggy game, on the last level, I had to select a starting location by hitting the start button somewhere on the golden block's descent through the level. On level 20 sometimes one of the blocks on the slide(the 2nd one) falls out.
To beat the last mission, "bloom" your mines quickly, don't upgrade your mines, and get plenty of energy. Use basic lasers, and sell them back when they aren't in the right spot.
