Stylistically great game (although why the ground-shaking when I run? Yeesh), but gameplay is lacking to say the least. I hate platformers with spike pits I can't see coming. Fighting isn't fun and the game overall is stupidly easy. Nice to look at for a bit, and great work on the cut-scenes, but overall not an outstanding experience. 2/5
Very cool concept, fun, but usually too hard. Even when I find the solution on a walkthrough it takes me 10+ tries to do it myself sometimes. Not a plus. 3.5/5
Yeah this is a really good START of a game, with decent physics and a bare-bones gameplay model. But to be a real game it would need better level design, a minimap probably, more depth of control, different/varied objectives or enemies, and definitely better graphics. Among other things. 1/5
I really like this game mostly. The concept is an innovative marriage of two traditional game-types: fill the area while avoiding obstacles, together with a physics-based model. The idea really works. But there are some problems that prevent me giving 5/5. The physics has issues that make the game more difficult - when I trap the enemy balls too well, they just teleport back into the game area, which is frustrating. The balls don't seem to behave properly (force is emphasized at the expense of mass; that is if you drop a small ball on a large ball that's already well-positioned, all the other balls will rearrange, which seems unrealistic and/or counter-intuitive) at times.
I love the idea, but absence of any sort of additional challenge modes, powerups, some kind of tweaks to enhance replayability, and with the physics mistakes, I cannot give higher rating than 4/5.
Really good game just not QUITE as good as it could be. Bugs me that I can't jump over arrows. Not enough spear strategy. Visible screen area could be bigger. Little more finesse in the controls would be nice. Game gets repetitive. All that said, it's fun to play and I love the heads rolling. 4/5
Challenging and fun! Walkthroughs not necessary, just some thinking and trial & error experimentation. Very creative concept. Only drawback, not enough levels. Two thumbs up 5/5
Good concept, pretty good gameplay, but balance is way off. Much too hard early on. I spent most of my time running around looking for easy stages just to get a usable tank. The purple blob is way overpowered, if you're unlucky enough to run into one it's bingo there goes 100 bubbles before you can do anything. 3/5
I had to revise my review down to 4 stars because once you get to level 4 or so and unlock High-Grade Starting Gems the rest of the game becomes trivially easy. Aside from that I find the game incredibly addictive and replayable up to that point.
