Rock Crush

Rock Crush - 2012 Special Edition*Future updates depend on you rating this app or a review - Thanks!System Requirements:A Mac with a screen resolution of 1024x768 or greater.Mac: OS X Snow Leopard or later.Keyboard and optional joystick supported.X-Arcade sticks are supported also (In Mame Compatible Mode 1).Aim Of The Game:Guide Diamond Dan around the screen and collect all the diamonds in each levels, whilst avoiding the rocks.There are 40 levels spread over 4 level packs of 10 levels each. There is a linking Warp Zone - collect all the diamonds in this to complete the game!Try to also get the high score of 99999.Strategy:You can go for either a time bonus for completing each level in the fastest possible time, or a perfect mining bonus for digging each bit of untouched earth on each level.On some levels (by design), a perfect mining bonus isn't possible so maybe the best idea is to go for the time bonus in those cases!Go for speed when you can - it helps to learn each level but that will come with playing.This is more a puzzle than an arcade action game but you can't stand still under a rock for very long! Good reflexes needed to play fast or else play it extra slow and cautious!Check out the new gameplay videos with hints below - this game is supposed to be played FAST!!!Move Dan using I, P, Q and Z.If Dan gets trapped, press Enter to end his life.Press Escape key at anytime in the game to exit.For a full list of keys - see the inbuilt game help system that appears on launch.Joystick Support:Most analogue and digital joysticks work fine.Support has now been added for the X-Aracde stick, when running in Mode 1 (Mame Compatible Mode).In this case, the left most joystick is used. The Fire button is the top left button on the left section.There are 3 graphical modes to try:Original ZX81 graphics - a pixel perfect rendition of the original "High Res ZX81 Game" (choose either with or without sound for the ultimate experience!)The 2001 Re-write Colour mode (Rock Crush was re-written for PC's at this time and featured Colour Retro graphics).The 2012 Re-write Mode! Enhanced new modern graphics suited to todays screens!History:Yes - A genuine ZX81 High Res game - in the App Store!For all the Sinclair ZX81/Texas 1000 owners out there who may remember the original game - good news - this is a pixel perfect rewrite!It's not an emulator but what you see on your iPad screen and how it feels is exactly pixel perfect to the original (when you select original ZX81 mode of course).The first silent, black and white ZX81 game in the App store! What a selling point eh?Ok, so at least you can play the modern modes as well but if you are a true fan of the original - try the silent black and white mode! Its quite peaceful!Rock Crush was originally written by Steven McDonald, back in 1985 for the 16K ZX81 computer.Those old enough to remember will recall the machine had a very Low Resolution black and white graphics display and had no sound.Rock Crush used a special HIRES graphics driver that allowed a quality of display not normally possible! You see, the ZX81 generated its own TV display, so it was possible to play trickswith careful timing and force the display hardware to do more than it was designed for by the original engineers and programmers of the ROM chip.In essence, ZX Spectrum screen quality, without any additional hardware!
