Well my 1 suggestion would be to remove the cheats / debugging buttons.
If you zoom the game in the window shows the:
I want to lose
Kill all Enemies
All Monies
All Research
options.
For me this game was a sinch, bout 1 tower and didnt build any more, very easy.
Might be harder without access to these things...
If you start a round, then exit via pause, go back to main menu and practice, hover over the course then go back to start round, and continue, you continue from that course???
You need to make it so that the screen forgets the intro every single time i play, dying here mate.
I have played level 21 30 million times and have to click skip every time?
....
Also would like a little bit more scrollage :/
Nice game though.
God grind like hell guys grind grind grind...
Also now all that grinding will pay off i will get game completed badge -- oh wait no glitch glitch glitch
