<edit> This version has since been updated to V1.00.
For example, user Pomf recently reported that TU2 running at 4k would cause his 4k TV to switch to 30hz (note that this doesn't appear to be the case on 4k monitors).
On further investigation it appears TU2 was creating a 4k window a few pixels wider than 3840x2160. This update tweaks how TU2 handles screen resolution in order to create a correctly sized game screen (hopefully this will fix Pomf's issue).
Fullscreen_exclusive toggle added to game start dialog box.
When enabled, this will start the game in exclusive mode, correctly sized.
In this mode, alt-tab will hard switch out of game but note that some texture problems may occur on using alt-tab to re-open the game window.
Toggle Fullscreen_exclusive OFF to be able to alt-tab to other programs in a safer fashion.
Alternatively, uncheck the fullscreen box to choose standard windowed mode with/without border.
Still to do
There are small $ symbols next to various upgrades on the upgrade screen.
These will allow for upgrades previously locked in to be sold for upgrade points - but at a reduced rate of return.
This is so that a player can still gain points if they don't have enough to sabotage the Megatower and it's about to be completed.
