This tech demo lacks real gameplay additions, the only ones I did are:
New player model
Walking/sprinting (hold CTRL to sprint)
Autowalk button (X)
Inventory tooltip autoshrink
Inventory has its own context menu on right mouse click
I've added a small NSFW secret on the map just for fun.
Next tech demo is a huge core rework (that is already done but I want to add a bit more features to it before releasing). It has a proper resolution scaling, UI scaling, better structure, and overall better quality, especially graphically. It will also add much more gameplay features (better inventory, equipment slots, stamina, looting, base for dialogue system), and we'll say goodbye to computers since they're not really needed in the game right now.
Sixth build should finally introduce some NSFW mechanics and economy, trading, stuff like that.
I'll also improve player model face and hands a bit.
Love you.
