These kind of games remind me the famous [Apogee](http://en.wikipedia.org/wiki/Apogee_Software) games that many hours have given me joy. Although with high difficulty, the *SQRXZ* saga have a version for all platforms... including Raspberry Pi.

I leave the link to the web with all parts. Hope you enjoy!
