Hi,
Sorry for the inconvenience running the game.
I have downloaded the kigen_windows.zip file and it is running successfully. There are some friends that tested the game without problems as well(I asked them to test the build before submission). In fact, a twitch streamer already ran the game a few days ago, like 10 minutes after submission.
Some questions: Are you using windows to run the game? Are you using another architecture different than 64 bits?
On the other hand, the credits are in game specifically in the screen that appears after the last battle. I am using resources from 5 different OGA community members.
I hope we can solve this problem :S
