8-Bit Night predecessor now on Desura for FREE! Alter Ego is a clever retro styled single screen puzzle platformer with an interesting swapping mechanic. You control a blueish little guy and his phantom alter ego (that moves in a mirrored fashion) at the same time. Swap places with the invincible alter ego to reach normally unreachable corners and collect all the pixels to solve each stage. The game is freely available for PC, NES,MSX and ZX Spectrum.
Fun and enjoyable and it's free, you can't go wrong with that. If you enjoy platformers and/or puzzle games you'll like this. I just played this after finishing 8-Bit Night so I found it a bit easy but only because my mind was already oriented for mirror imaging.
If you enjoyed this you should check out 8-Bit Night as it uses the same game mirror mechanic but with some other fun additions as well as improved graphics and music.
