This was extremely good once I was able to properly play it, but I spent around an hour wandering the first section, as the audio seemed to get stuck on the delivery point and I couldn't manage to navigate the loop points to it. I even partially decompiled the game and found your tilemap that shows where they are, and only barely managed to stumble into the right path after trying a ton of times. After that I managed to get through the rest quite easily using that tilemap, because I had spent so long at that point I didn't want to bother making my own. This leads me to my suggestions/criticisms:
- The sprint speed should be the default one, or move the sprint button to shift, as holding ctrl hurts your finger after a while.
- There should be some kind of built in mapping feature, footprints that you leave as you walk, or at the very least a compass to help get your bearings (The instruction to go north only made sense because I had the tilemap).
- I think a better way of doing the first section where you follow audio would be to have the audio player on a path that it moves along as you get near it, instead of jumping to set points. I found that even if I could tell exactly where the audio was I would often be on the other side of a wall from it, then have to find another way around (Granted it would be a bit more complicated due to the teleports).
