Played this with headphones and it did not disappoint.... Audio and game design were spot on and I really like how the theme was central to the gameplay loop. Everything contributed really well to the immersion. My two pieces of feedback:
1. The controls were rather sensitive. It did make my character look like a terrified mess at times (suddenly looking behind him XD) but I think maybe this could be tweaked?
2. Some parts were rather dark (getting the tools for example) and meant it was a bit tricky to see. I realise the design choice behind this, so perhaps making the torch (I think that lighting was from a torch) more powerful would help?
Overall I really enjoyed it! :)
