unfortunately they falsely advertised twice. they deserve the criticism in this case. it sucks that it isn't entirely their fault, but they still did wrong.
Of course that he deserve some criticism here since he did some mistakes and admitted it, but the problem is, people literally pushed him TOO much, they didn't give him a break, that's not just right. If you want to give him criticisms, then do it in a constructive way, not just pointing out his mistakes while he couldn't really control it anymore, not to mention that some people even insulted the remake so bad, imagine having to face all of that both from Steam and Itch.io when he already worked so hard and hoping that his game would be popular again, knowing that only to be ended up in such horrible situation like this. I can't imagine the problems this dude have to endure during all of this negativity, i hope he really take a break from this.
