Thanks for the answer! For the upgrades, i meant for example the "enriched uranium" thing , i had buyed a few so yesterday, the uranium thing was: "4 heat pulse for 120 ticks", today when i opened the game again, it was back "1 heat pulse for 15 ticks". I think that is a bit strange, isn't it?
It is a great game, but there are still a few problems:
* yesterday i stopped playing. The game saved, but when I opened it today, the upgrades I purchased didn't work anymore. I could'nt buy them again, but there benefits were gone.
* So I decided to reset the game and to start over, but that seems to be impossible: by reseting my money went to 0 , so I can't buy anything, so I can't play this game anymore. I think this is very sad...
