the hardest part of making a RPGmaker game is being stuck with that battle system, which is the hardest thing to reprogram. I don't know if I made another game with it if I would have battles at all, or come up with something different. That part of the game isn't really your fault.
As far as the content, people are just fucking stupid. As an adult, I found the flavor of the game refreshing.
Some people don't know how much work goes into stuff like this. I've done it myself, and I appreciate that every little detail needs to be painstakingly taken care of.
As far as gamejolt goes, it's too bad the trolls have the upper hand. Some people lack the experience of having real problems.
I think your game development has been highly successful: first of all, you finished it. Second of all, you made a mark... even if it wasn't what u wanted. you've gotten a lot of negative attention, but that's better than no attention. Most of those games are just remakes of other games. Your game is definitely not one of those.
I always tell myself that, even though I am an unsuccessful artist, I am at least still an artist. The vast, supposedly uncaring universe does NOTICE when you take it in your hands to create something. And even if it seems like no one cares, you've still done something amazing. That's the way I feel anyway.
