Yeah I had to give up 2 runs because on the 2nd to last level I ran into impossible to escape scenarios. The first time was while exploring, a jump pad sent me to a impossible to escape platform where I could only suicide to get out. The second time was a puzzle involving directing lasers, (which somehow damage you no matter how far away you are, another bug), which generated a impossible to solve solution. What I mean by this is that the nodes you use to direct the lasers are destructible, and generated in such a way as to make solving it impossible making my run useless.
This is disappointing as I was enjoying my time with the game, and was looking forward to finishing it. I can't even look up a playthrough to see how it would have ended, as so little content exists for the game on youtube for example.
Sorry about the issues with the beam puzzles. I double checked the Level 5 puzzles for the latest patch and they should all be solveable, some of them seem a bit too confusing for a lot of players to figure out though. We'll work on telegraphing the correct path of the beam better in an upcoming patch. I haven't heard of the beam damaging the player the way you described but we'll check into that too.
Level 5 is the current end of the game so you didn't end up missing out on that much content. When we leave Early Access with Patch 3.0 Level 6 and the game endings will be added.
