Excellent play
All in all this game is an improvement from the first one. I liked how you integrated having different timelines such as the Past, Present, and Future. This keeps the story fresh from the first one. Additionally, this one is a lot easier and less frustrating from the first one, however this one might have been a little TOO easy.
The weapons were not as effective as I thought, thinking that the most recent weapon will be able to out-gun the previous one. This was not the case, and i ended up not using some weapons entirely.
Aside from the easiness factor and the problem with the weapons, this game does just what it was meant to do: entertain. I had a lot of fun, and especially loved the flying penguins.
I look forward to your future developments!
