I believe it's level 4. One of the puzzle pieces is not spawning. I tried replaying the level several times. I also quit game and restarted a new one. It didn't matter, each time the puzzle piece never spawns. I have seen a YouTube video of another player and I saw the puzzle piece spawned for them. I know I'm not the only person with this issue because I read another reviewer (German) mention he had the same problem. See problem here: https://youtu.be/LMvmSdX18Pg...

When you try to start the game, Steam says "no controller configuration found". The game itself shows no controllers.

So we can produce more of it! We just need some direction whether the levels (escpecially the later ones) are too easy, too difficult, too boring, etc. Thank you!
