Wow. Quite a weird experience. But I must say that I enjoy it. Just one small issue I run to... the mouse/view speed is EXTREMELY high. Happily my mouse have DPI control button, but in the default mode... it was impossible to control it.
The music was creepy during the gameplay... but I guess it's correct due the fact that you're "punished" to rewind the tapes. And the final music was excellent.
Good work! Congratulations!
