Random mode should now correctly assign you random towers if you have already played a level in standard mode.
Clicking the upgrade button without a tower selected will no longer crash the game.
Blade tower will now only fire at enemies within range 7 instead of anywhere on the board. The blades still travel off the screen as intended.
All target towers will now have the target hole correctly displayed in the center of their hexagon.
Updates
When returning to the level select screen the selected/previewed level will revert to the most recently played level of that session. When starting the game it will still revert to level 1 "Rattlesnake"
