Boulder Dash and Supaplex mash
Rockford is not a complete clone of Boulder Dash, though it certainly has a lo9t of elements that will remind you of that classic arcade action title. It's not completely a Supaplex clone either, but some of the elements of that game are to be found in here. So, what it is, is a game in which you play this explorer of underground caves, full of elements that, at any time, can move about and fall over your head. You are moving about in the game in order to get the crystals, and when you're done, head over to the exit. You can take multiple roads, and you can bore your way around, but make sure you don't destroy some of the elements, as you might end up with a bolder fallen over your head. The game is smaller than Supaplex, with just 6 levels/worlds. You can increase the difficulty, which will put more boulders in each level and you can choose which avatar to use, from the 4 included. Also, except for the boulders there are also active enemies roaming about, which you just need to avoid, or capture them in the debris so they won't be able to follow you. A great, if fairly small game, great for those looking for an arcade, action/puzzle mash-up.
