denying people a way of trying out your game while demanding money from them to support said game seems antithetical to me.
You have not spend that much time around the Gaming Industry in the last 15 Years, have you?
Most Developers stopped making Game Demos right around the time the Steam Platform started to take off. Ever since, whenever you wanted to try a game, you had to first buy it and then hope that you are still able to get a refund.
This has nothing to do with ethics but with business and, if you where to think about it, that's how it works in "Real Life".
If you really where to want to Test the game, there's always the lowest Tier of Support on the Patreon of only 1$, that will immediately get you access to the "Censored"/Test Version of the game. So go ahead, buy the Dev a Cup of Coffee and you will be able to test the game to your hearts contend. And if you do not want to then don't, it is your decision. But do not start with ethics on this Site because, if we where to be honest, the Ethics on this Site are questionable at best.
Damn, someone is really going out of their way to keep this game off the forum.
Could be, could also just be that some of the Accounts used on the Upload sites got blasted by the Site owners for not following guidelines (as in Uploading and sharing someone else's property against their will). We might never know. But hey, the new Release is supposedly just around the corner, so why bother going through the trubel now for it just to change in a few days/ weeks?
