Yeah, slow-mo looked more like lag that slo-mo. I suggest you look at an example so you just don't reduce the room_speed.
Also, I really was looking forward to someone making a clone of MW2 platform/TDS. I seriously was. But this really exceeded my expectation. Instead of a dull platform shooter, I flew a weird helicopter, manned turrets, avoided falling blocks, etc. Also, the thing that makes this game so great is that it's short! I don't want to spend more than hour replaying a game I already played.
+1 for having the "This isn't the message; this is the message", haha
Also, can you PLEASE change the ammo amounts to decent sizes? I felt really weird shooting out of machine guns with 10 bullet clips. You can spawn more than one enemy at a time since I noticed you only do one or two at a time. One more thing is that you shouldn't spawn enemies out of thin air. Just have them standing around and attack you if they're facing you and have a clear line of sight.
Anyways 9/10, great game! This really doesn't need more content updates, just some of the changes I said above.
