Does it create an "error_log.txt" in the root directory of the game, and if so can you please share it?

it was a problem with my antivirus. it happened with another itch game too. i turned it off and the game worked fine.
thank you for the help and best of luck with the release. i will surely encourage you again with the switch port when i grab one later this year. on the go is better for this type of games.
