Thank you, I really appreciate such a detailed and honest feedback! Glad you liked the destructible terrain. The [R] button is meant to be hold down, actually, - this shows a ghost of yours from a few seconds before, and this is where you’ll be teleported when you release [R]. Didn’t make this clear and many players have commented on that, my fault.
I’m sorry but could I ask you a few specific questions? First of all, when you say about rotational sensitivity - how many turns does it make per second? I’ve heard a few times about this issue and still don’t know whether there’s an actual bug or it is just a personal perception issue. Secondly, what screen resolution did you play the game? The scale is resolution-independent which seems to make the game hard to play at low resolutions.
Thanks again for your feedback!
