Thanks for taking the time to play the game! Thanks for the feedback, it might be due to the fog that is causing frame rate issues, but also I didn’t do any optimization :D I know the accidental select is frustration, I wish I had more time to find a nice solution to it. About the assets, please give some love to these guys:
