You should definitely make the intro skippable. Once I died, I had to watch the whole thing again. Also, I didn't know that I had to press space to continue the dialogue -- I tried clicking, enter, etc. and assumed it was unskippable or something. I see that it is written below, but there should be a prompt in the game to tell me what to do.
It's hard to give feedback on the gameplay because I could only play so many times before the intro sequence (while it is cool) got old. Also, there was no instruction on how to play the game so I just had to press random buttons and my hook got sent out into space and never came back.
