Pressing 'A' at the title screen does not work.

at lvl 2 I cant make the boss apear, the path stays blocked

After i choose my save slot, the game just sits at a black screen no matter how long I sit there waiting for it to load. This game is literally broken

The game for me is currently not working. I start it up, and 9 times out of 10 the instant I click on one of the menu options it breaks. The main menu remains on screen, even though I can hear moving up and down, and it has a similar problem with starting a new game, where it will go to black and then you can hear things happening. Is there a large number of people having this problem?...

Anybody had this too? No issues in the game until the first futuristic level (the one with the secret teleporter). I had the sound cut out completely, clip through scenery without a way of getting out, the valves don't work 4 out of 5 times and one time when he would finally turn the valve he moved a bit out of himself while turning and didn't stop turning the valve.......
