The planets are gone and enemies now ramp up until their are fairly unstoppable, I’ve played and tweaked the game last night and the longest I’ve lasted was about 28 minutes (thanks to some defense stations) before succumbing to the onslaught.
Few more tweaks and this morning to the installer to make sure it is consistent with the older iteration (same install directory). The installer now also creates a link to the manual in the Programs Directory, minor but important things like that.
The major goal for iteration 4 will be to have a semi complete tutorial, in addition to the usual tweaks and fixes. The nice thing about starting on the tutorial system is that the same code will be re-used for the story mode, since a tutorial is basically an objective based sequence of events, same as a story line.
Hope you enjoy!
