Thanks Umamisoft for your comment!
Glad you enjoyed the game overall ! :D
I think you would have had a much better experience using a controller for your first discovery of the demo! The keyboard inputs are really only advised if you have already played games like Celeste with a keyboard. Inputs are easier to get used to on a controller!
Otherwise, the dash is also bound to the Right Mouse Click at any time, did you notice it? Also, you can rebind the dash located on the right shift key to any key you like better! The right shift key normally allows you to dash with your right hand while you handle movement and jump with your left hand using the WASD keys and the space bar! Maybe you used the arrow keys instead of WASD and then of course, it might be difficult to reach the right shift key then i guess!
Thanks again for playing ! :D
