Hey, thank you for the thorough feedback! I appreciate it.
"Some of the levels, however, I felt like I was trapped, and that every couple of seconds I was back at the spawn without really understanding what had hit me or what I had messed up on"
I thought about this, there's no proper game over screen and you indeed immediately jump back to the start. The losing mechanic isn't really something I worked out, the player just needed to not be able to blindly run through the drone sights.. There should indeed be a more proper indication of what happened and how, either through sound and/or visuals.
Maybe in the early light switch level you ran into the spikes near the end and it just restarted, I'm not sure. I doubt the level would repeat itself, I tested a full playthrough before release.
Thanks again for taking your time to leave such helpful feedback! It's greatly appreciated.
