Can you out-smart the alien space squid? Plucky space repair robot Space Bot Alpha finds his space ship has been invaded! Alpha can use his shields as long as he's on the ships power rails. Guide him to build walls and seal off the levels. But watch the wily alien! His touch is deadly when Alpha is out wall-building, and away from the power rails! Flash-bombs and energy powerups can help Alpha, explore the levels to find them before sealing it off. Once 75% of a level is sealed, the win is triggered with 1 star. But the more you seal off the more you're face to face with the evil space squid! Only top skill Space Bots can get 2 or 3 stars!
About the last feature - social sharing - is now implemented. This is a screenshot of actual game play generated by using Cocos2D's CCRenderTexture node, captured to a file, and then shared via the in-game "share" feature on the score screen. From here, polishing!
