Cool idea, narrative-wise felt a bit like Portal / The Stanley Parable (which is a virtue, ofc.!). The hard level is properly hard :-)
I hope it wasn't too hard though! I often have a hard time balancing since I'm usually the only one testing my levels. Were you able to finish the game?
To be honest, I haven't been able to finish it - I played it on the hard level first and wanted to retry today on the easiest, to get a comparison :-)
Okie, I've replayed on the easiest difficulty - I got stuck at the boss level though :-(
Nonetheless the game is turbo fun - I love the ads' descriptions :D
