Dude, this is next level! I'm shocked at how complete your game feels. The sound and environment design had me completely immersed, and the tunnels section in particular was genuinely pulse-pounding! I never got confused or stuck, but I also never felt like I was being railroaded; that's a difficult balance to strike and you nailed it. Clearly this is not your first rodeo, and I'm excited to check out Spirit Level next.
