Well, I mean, that's one of the reasons you're putting it up here for us to download and play, right? Let us players tell you where you f***ed up. I only hope that MOST of us here are at least nice and polite about it, not angry fucking jerks.
Most of those bugs we are currently seeing are "Parodos' errors'" in the editor rather than plugins causing them, so those are quite easy to fix. Mostly missplaced commands in events which he didn't notice before release. Easy to spot while playing the game, because even one single missplaced command can simply fuck up whole even chain, yet a bit more harded to notice in the editor, especially on long and/or branching events, because RPGM is quite rough around the edges in terms of helping you.
Reporting bugs you found is not mandatory, but surely it won't hurt anyone by doing so in order to improve the game by letting know people resposible for making the game about something they either forgot to or didn't have enough time to check.
I would say more like to find bugs rather than "To tell the developer where they "Fucked up". Bug finding is a part of developing any game and even AAA titles like Poke'mon X/Y had gamebreaking bugs upon release.
Well, telling a man resposible for making a game that "he fucked up" ain't the most nice way to say it, but it's the blunt truth. He made a mistake and thus there's the bug which wouldn't be there if he put a bit more effort into testing.
And yes, sure, bugs are part of developing any game. They are inevitable, no matter if game is made by a single person, or a hundred. Even more so if there a multiple teams working on a game. But there is a bit of a difference between a single man indie developer and a studio throwing AAA games. First one fucked up with bug hunting, due to the fact his day, just like yours and mine, had 24 hours and he didn't have enough time for it before release. And that's understandable and we may let it slide few bugs here and there but only as long as he won't overuse our trust. I may even do some true bug hunting if I see current developer is actually the one that cares and report few bugs I managed to find, especially if the game is free.
It ain't much, but it's honest work.
Second one is releasing paid unplayable game with tons of bugs expecting from players to do free bughunting and is simply awaiting for reports instead of actually hiring enough people to do bug hunting before release. That ain't nice. I payed with my hard earned money for a game, so I want to play the game. Not to be a bug hunter, and certainly not to write multiple reports about bugs I managed to find every two steps which will never be fixed anyway, because they are of "minior importance". If I wished to do some bug hunting I would be making my own game in my free time. And I am still wondering why we, gamers, are allowing for this and more downright wrong practices of big game making companies.
