This is bullshit...
I really do understand working on a game like this one is expensive and time consuming, but competition these days is quite resourceful, so if You're getting into business not knowing that, You're simply not well aware or hoping for some quick money grab. Ordinary folks are not able to spend extra bucks if they can't be sure You're serious with Your project, so to get some You need to give some first. If dev is giving up after barely 3 months, sorry, I can't even consider he was ever serious.
This had potential... could've been sth great... I know it's tough but won't get easier over time.
Now I devote a minute of silence for another one who has fallen.
