This is a really cool game. The minute that sound came through I thought OK, this is HL + Opposing Force. Really love that vibe about it or at least the references (if intentional). While the pushers were annoying, I think the main villain are the ladders. I keep falling off them and can't climb them straight. So many deaths because of that. Not complaining, the whole experience was pretty fun. One thing though, I reached the part after all switches were turned off and then I found myself at the elevator that brought me up. So I hit it and waited a bit thinking that is what I need to do but nothing happened. Not sure if I broke something.
Really good game, would love to see a full fledged game out of this. Good work!
