Planet Juicer

There should be a way to remove the orbital mines after placing them. A mistake placement will result in loss of a defensive space.

If you wanted to replay the previous levels, you have to click the current challenge first, that needs to be changed to ease confusion for the "easy go-ers". Also, with just the 3 levels, I don't see how the "hard-core" gamers would want to keep playing, there should probably be one or two more (difficulties of "extreme" and/or "nightmare" with 25-30 waves, respectively)

the only thing i could add would be for the melee type units to have more hp against ranged, in the tank levels they are completely useless because they die so fast

as Tenchi said, you need alot more than 3 levels. At least 3 easy, 3 medium, 3 hard, and an extreme. That way people dont have to replay the levels.

Graphics and sound top notch, wouldn't change them. Story... too short, but add in another 6-9 levels and we have a challenge. Maybe an endurance/endless mode where all the different planets come and invade the home planet? Overall i did see a few issues. if at the end of a wave you have the build menu open the game just hangs till you get out of the menu. (sometimes as long as 45 seconds after the menu is closed) Also im not sure if its meant to be this way but your top and bottom lanes get next to no attackers, on many levels i just had a single gunner in them and that was it... overall i didnt think the jump between levels was too bad, starting with as little as 1000 on each level i had little issue. overall 4/5 just because it was a little too short.
