OK hope this works, it's just a few levels in JAVA so should work on pretty much any old mobile phone:

The game is played from a birds eye view and Repton has to work out how to get past each level by dodging rocks,pushing rocks, collecting diamonds, running from spirits, teleporting to places, solving puzzles, breaking eggs, killing monsters with rocks... and more.
The thing I loved about repton so much was that you could deisgn your own levels and even change the graphics.
Here is a PC version of Repton to try:
