Thank you so much for playing, Gibbo! I'm glad you were able to get used to the controls and movement. Keyboard controls are something I'm still kinda massaging, the game feels a lot better on a controller. I'm glad you liked level four, I'm really happy with how the elevator mechanic worked out!
Yes, the settings menu is something I'm working on. Should be able to have it patched sometime next week.
Thanks again!!
