Thank you for your comment, glad you had fun with it :)
One thing I was itching to change after the deadline was the rushed instructions screen, it was done at the last minute and I even forgot to mention space is jump!
There was going to be a map pickup that, if found, would show you the whole area and where the key is. It would have shown much more clearly the 'web' layout but , despite implementing about 90% of it, I had to drop it at the end. Post-voting I intend to put it back in :)
