It seems that all of you who guessed Cave Chaos 2 were right, it is Cave Chaos 2! Nitrome provided an image, but it isn’t clickable. The art for this game looks absolutely magnificent, probably the best art I have ever seen in a Nitrome game, being similar to Nitrome Must Die’s art. Nitrome hasn’t specified when this will be released, but seeing how past Nitrome games have gone, we should probably see this sequel in a few weeks, or 1-2 months.
Mysterious sequel revealed – Cave Chaos 2!
