I am the author of this game and it was created in order to fulfill requirements in practical part of my Bachelor thesis - also my first ever game released for mobile devices.
I tried to keep it fairly simple - the basic idea is to build time generators which generate time (obviously) and use that time to build other structures which help you defend the generated time against waves of intruders. The thing is that the 'health points' of the structures is represented by time. Every structure needs to be placed within time generator's radius in order to 'get charged' (ie. built). Of course, their time is decreased once they are attacked by enemies. Eventually, you should get to the point when you have enough time to build a Time travel machine that, when built, will end the game.
It is indeed inspired by Rymdkapsel.
I understand it is not the kind of game to keep you entertained for weeks but I believe some of you may like it.
Thanks for sharing it Pete.
