In 3nyan Quest there are three different endings you can go for and quite a lot of areas to explore and puzzles to solve. Really complex yet fun to play, this is a title of a really high quality all fans of the genre should try.
Also remember to check back a bit later here in the Unigamesity if you get stuck, as I am going to write a walkthtough for this great title! Until then visit this link and have fun trying to finish 3nyan Quest!
UPDATE: As promised, here is the 3nyan Quest Walkthrough.
