If you feel like testing your mettle against a good brain busting homebrew puzzle game for the Sony PlayStation Portable, then you may want to try out developer Wallaby's Dark Basis. This interesting homebrew title is basically your standard two-dimensional maze navigating game.

However, while the premise of the game may be quite simple, the mechanics behind it get progressively more challenging as you progress through it. For every stage that you get past the first one, succeeding levels will offer you multiple exit points.

Now for the bad news: only one of these exits will lead you to the next level; any other puts you back to the first stage's starting point. The game may be frustrating for some, but it definitely stretches your mental facilities in trying to remember the entire layout of every level.

This demo version of Dark Basis only sports four levels so far, although the developer mentioned that the final version will have as many as thirty stages to navigate through. If you feel like giving your brain some much needed exercise, go ahead and download this game through the link we've provided below.
