Thanks a lot for taking the time to play the game and write such detailed feedback! I'm really glad you liked the ambiance, visuals, and the moving platform boost.
About the keyboard, I'm sorry about that. I had honestly never heard of the BÉPO layout before, so I only tested with the standard keyboard layout I use in Unreal. I'll definitely keep that in mind for future projects.
The debug keys are actually leftover debug features from the ALS movement system. I think you probably found them because you were trying different keys while figuring out the controls with your keyboard layout . I completely forgot to disable them for the jam build.
You're also right about the music at the second and third level . I added it at the very end and forgot to hook the music into the audio mixer, so that's why it doesn't actually affect the music.
About the moving platform boost, that part was intentional. I wanted players who discover and use the momentum to be rewarded, but I also tried to make sure players who don't use it still have enough time to finish. When I tested the levels, I timed each section so if you reached a platform with around 1–2 seconds left on its countdown, you should still be able to finish the rest of the level.
I think where I underestimated things is that I've played the game so much that I naturally know all the little movement tricks and the best route. For a new player, it's probably much harder to tell whether they're doing well or already behind. Better feedback would definitely help there.
For the third level especially, I intentionally made it much tighter. It's meant to be the hardest part, so losing even one second can be enough to fail.
Thanks again for the awesome feedback! Comments like this are really helpful, and I'll definitely keep them in mind if I update the game after the jam.
