Thanks for the feedback !
The total lack of sound effects (and the somewhat crappy quality of the music) was of course a consequence of the tight time limit of the competition. As we cannot reuse anything, I would have had to record everything I wanted to use in-game during that weekend, and as this game was my first real project with panda, I didn’t have enough time…
As for your other two suggestions : the non-linear levels are implemented. I want to take this into something a bit deeper, and while I want to keep the genre, and have your character accelerate automatically and have a obstacle-dodging gameplay has the core, I want to give the player more choice about how he’s going to move. So that’s in the works.
The narrative in its current form will also go away. I don’t have yet every details, but I think I have a pretty good idea on how I will at least present it. It’s going to be better than walls of text 
Thanks again for the feedback, anyway !
