Quality of life updates in the demo — Heroic Assault Steam update #536400

There is less than one week before the release of Heroic Assault! I am working on some minor tweaks and quality of life updates to improve player experience, after some feedback from the demo. The unit shortcuts at the bottom of the screen have been reworked to be more aligned with what can be done in RTS games. The key mapping has been moved to the 1-9 keys and groups are now matching the wave structure, allowing to selected units with more details and be more efficient! Left clicking on a defense will now show a bit of information about it, so you know what you are dealing with with more details. Quality settings have been fine tuned and the disk size has been optimized All of those changes are available in the demo, which will stay live until the day before release!
