i think the red mini helicoptor game is slightly too hard compared to the others the space is not that responsive and you fall quite quickly when not paying attention. other than that a very good game !
i built a "great cannon" with great expectations as the name and price tag suggests but i felt a bit ripped off that its practically the same as the previous 2 cannons. i dont think cannon instakill should be changed but either a much greater reload time reduction or shrapnel or something for splash damage
