Just got around to playing and beating v1.5 and can I say fantastic and tense little 'puzzle horror' experience based around figuring out how to work around the AI's behaviors to complete objectives. Took me until the finale to figure out that grass muffles your footsteps - for better and for worse, worse being that the finale felt like it was more 'puzzle' than 'horror' where you have to plan the 'perfect route' and cheese the AI with the alternative being stuck in an unwinnable chase by the 3rd/4th battery.

P.S. if 'cobb can die' then he should be able to be killed with rocks, would be a funny outside-the-box solution given the Baba Is You influence.
