Fast paced and a simple concept that combines creative aspects on one hand and heavy platforming action on the other. While this game defiantly shows its strengths, it also shows a few weak points.
While yes, bosses are supposed to be typically more powerful than the player, the power balance here almost feels unfair at times. While yes, you MUST defeat the boss before it can be posted, I feel that at times some battles are just luck. The other issue is that the secondary to the human players, the flame thrower, might as well be a pea shooter because it does next to nothing, only buying me time until I have a power shot handy since it is all I have. Human players shouldn't have as large of a weapon base as the raybots, but they should have something more than a cigarette lighter.
Level designing was a total breeze with it being both simple and easy to work. Pattern programming feels a bit hit and miss though. There are times when I would like to pause at a certain point to let myself think about what I really want this raybot to do, but instead I have to pump all the commands in one go, making what could be a very neat boss design look and feel like it is missing something. If we had something like a pause feature in pattern programming, I feel we could see some more inventive bosses.
Overall, a impressive game that will prove itself to be fun to many, but before it can expand its audience, some more tweaking is needed. Heck, I could even see this being a good XBA title just on its own as is... though I still hope to see the above fixes, nonetheless.
