its a good game
Good game I like the "fill xx% of the screen" kinda games.
recommendations:
1. In normal games like this the side it usually fills is the one with less monsters (which i disagree on) and the one with just one monsters where. it tries to make the side without the monster...making traping the monster the best solution.
2. Did you ever consider you always have to use at least 3 colours ? motive => first you are limited to 50% max of the screen...then...ur can take an extra 25% of the remaining 50% and last hit would be the 17.5% u need to finish the stage... and as I saw it...after 5th color u get no extra bonus at all...
3. for future updates...try power ups... or at least something to change ur color especially in later levels where u always seem to put 2-4 of the same color and type of enemy in oposite ends of the table...which always forces u to take one down...unless u would rather waste 1 color (thus losing your bonus) to destroy the symmetry in the stage...so you can avoid traping monsters in there color.
