I didn't have a problem saving at all. Took less then a second. I recommend right clicking/setting/set to unlimited.
Good game, only problem I have is that you can sit in a boss fight and just collect a huge amount of money making the game easier.
I found a trick (or cheat depending how you look at it).
Build a TON of researchers early in the game when you get free resources and just max out all the research. makes the game super easy..
Would like it if it were easier to move the elevators. Since they are numbered 1-7 you should be able to hit number 1 for elevator 1 and then hit 5 for floor five therefore moving those elevators... hope that makes sense.
found a glitch, my arrowkeys where not working so i accidently right clicked and they still didnt work so I did it again and noticed a play button. I clicked that button and it brought me to the home screen were I hit play on the title screen to play again. It then brought me back to the battle I was in and the enemy could not hit me but I could kill them.
They bunched up at my castle not able to hit it and since I still am not able to move my screen I think it won't let me hit there castle either.
Had to refresh page. 4/5
back to 2/5 , too little lvls, enemies are way to easy, never have to use the guy and there is a bug that sends your guy to the right hand corner making him useless if you did want to use him.
after reviewing more of the game I rate it 3/5 for average as it isn't just a plain old rip off and the enemies do get harder even though it is VERY VERY easy... I havnt had to shoot in 5 levels
