I had an epic moment similar to yours where the Alien came out and slaughtered some humans, whilst I hid out of the way. I can't remember which mission it was as it was long ago, but towards the second quarter of the game. I just came out of hiding to then complete my mission/get to where I needed to be. Part of me felt bad for the humans, but then it was either them or me.
I don't think cutting some of the length of the game would have been a terrible idea. It's definitely long enough, so I don't think it would hurt too much. I did really enjoy the pacing during the final few missions and it was tense as hell, with an open ending to leave room for more. I just hope that they stay true to the spirit of this game and go for the same sort of vibe. I didn't get around to playing the DLC, but I did watch a run-through of it on YouTube the other day in fact (timing is perfect) to see what I missed out on and I'm very tempted to give it a go. It looks great.
I'd like to vote for Wario Land 4 please.
Despite having technically reviewed it twice (VCW #187 on 3DS and VCW#295 on Wii U) it will be interesting to see how the game holds up another four years on.
Interestingly, I think it's one of those GBA games which I probably own in physical form... but I'm not completely sure.
Had my braces changed from rotation to spacing earlier and it's the most pain it's been since the start. Hopefully it'll wear off, but at the moment I can just feel constant pressure. Plus I sleep on my side so I guess I'll have to trap my head between cushions.
