Really good game, made it to the end. The controls were confusing though. Here it says C is to jump but in the game, it was X. X for me was to jump and boost, while C was to Wall jump and boost upwards, so it was weird to have to press X to jump on to a wall, then have to press C to wall jump. Also every time I jumped to the left or the right, it automatically used the boost. I think it might be because it was the same button (X). I was also stuck for a couple of minutes on the fan part, I kept trying to boost through, then I went back and found the tunnel. It wasn't very noticeable since it blends in and I thought it was the background, (though after I found it I realized you were giving hints by letting the player go through the grates to the fans, I think that was very clever and I feel like I should've noticed sooner). This is really good for a beta. Can't wait for the finished product!
