Hey, thank you so much for your in depth review! I'm sorry you encountered so many bugs. Did the flying through blue walls occur on every level for you?
The jump height is fixed, so jumping from wall to wall is necessary if you lost too much hight throughout the level, an approach using the camera orientation might have been better in that case, I agree with that.
Every button in a level corresponds to a green door, in order to open the door you need to shoot a net at it. The net needs to stay on the button for the button to be activated. During playtesting we did encounter a few problems with the buttons hitbox, so that mightve also been an issue.
Otherwise, we are glad that you could still enjoy our game. Thank you again for your comment!
