So it turned out nobody liked the original mouse aiming system
This was not entirely a surprise as literally nobody had previously said that they did like the mouse aiming system, but at least I got some feedback and examples of games which had good mouse aiming schemes. What people actually wanted was not the direct input control system to player character rotation, but for the player character to turn towards a visible mouse based cursor or aiming reticle.
And their wish was my command! Had a bit of trouble networking it in multiplayer co-op mode at first but got an example of setting up a net event that would send the client input directly to the server object rather than having to wait for standard client/server updates.
It was also Steam Next Fest, were a thousand desperate indie devs got harvested for demo downloads so that gamers could get a badge and 55XP off Valve.
I ran two livestreams with varying amounts of success and terrible audio until I ironed those problems out - even though I had ironed those problems out in testing previously. Was hoping for 10% wishlist but got 1%, which is at least better than Sweet FA%.
Monsters Loot Swag will ship as an Early Access title on Friday, July 28th, 2022 - which gives me four weeks to get it into a shippable state. eg: make more boss monsters for the compeleted levels.
