I see... That was brought up by someone else, too. I'll admit I've been PC gaming for so long that "ESC = menu" is just naturally ingrained into me, so I was genuinely baffled for a bit when it was first mentioned by another reviewer. I guess that goes to show that a wealth of experiences for testing is important, huh? It's important to get stuff that you would've never thought of.
Thank you very much for letting me know! I'll see if I can include some control references in the game for future versions.
