thanks for playing man! Im glad you enjoyed it. I haven't tried the keyboard only controls to be honest. I thought it might make it harder because you can less quickly turn your head around to listen for sounds.
Fair point :3 I just feel like using the mouse and keyboard whilst trying to focus on listening for a specific sound can be a bit hard.
The hardest part imo was finding the birds in the beginning of the game.
Thanks for the feedback!
