Thank you for playing!
>FPS
As for camera, you can switch it between first person and third person mode, if you wish, pressing 'Tab'.
>lost myself occasionally
You can show minimap (press 'M')
>I felt that sound design could be better
Yeah, some of sounds is missing and some are templates
>Is possible to limit the FPS to 30?
Not really, that would ruin some stuff for game, and it would be more clunky with controls, as gamemaker would update only 30 steps per second, afaik
I'm glad you liked it and had fun with it :)
