Real RETRO feeling with labyrinth games, not more, not less...

Remember the old days when computers had 8-bit processors and 64kB only?

Remember the Sharp MZ-700 with it's SharpSCII graphics, Z80 processor, just 8 (Eight!!!) colors and not much sound?

It came with some prepacked games, one of them was MAN-HUNT which I really liked... and still do. So I took the chance to see how complicated it is today to implement such a game. Yes, writing a primitive screen driver was nice and a bit of work, but the game itself was not much trouble. So if you like this game and I see it is downloaded, chances are great that some other Sharp MZ-700 works of art will follow.

Why? Just found no emulator for Android running smooth and being in a RETRO-mood myself... It's been 40 years I coded on this machine in the first place, so the sentimental journey was very welcome.

You think the games are hard, real hard to win? Well, back then we didn't have much tutorials and entry levels like today...


NEW July 2022: Added 2 new games - now 12 games in total!

Included games:

  • ZOMBIE ATTACK - How many nights can you survive the attacking zombie hordes?

  • VETRIS - Variants of the classic with 5 different modes of play with critters, explosions or under extreme time pressure.

  • LUMBER BOB - How much wood can you chop? Interpretation of a late indie hit like it could have looked on the MZ-700.

  • SPACE SHOOTER - A version of a shooter game with auto fire and different enemies and attack patterns. New interpretation and combination of several classic arcade shooters on the MZ-700.

  • KNIGHTS CASTLE - Rescue the maid from the castle. Remake of the MZ-700 classic.

  • RESCUE PLANE - Help the stranded pilots to get to safe ground. Remake of the MZ-700 classic.

  • SKIING - The one game I always missed on the MZ-700. Enjoy cruising through the snow and avoid obstacles.

  • BOMBER PLANE - Clean up the ground to land your plane safely.

  • MAN-HUNT - Are you able to clear the maze completely? Even when there are more ghost coming? Remake of the MZ-700 classic.

  • PAINFUL MAN - is very similar to the old game: Collect all energy to get to the next labyrinth without crashing into enemies and before your energy runs out. Remake of the MZ-700 classic.

  • LAND ESCAPE - comes with some changes to the original game I always wanted 30 years ago. E.g. a nicer fuel and heat display ... Try to run and jetpack over and around the obstacles and get as far as you can. Remake of the MZ-700 classic.

  • MOVING SEARCHER - makes you collect all fuel cells to clear the level. Easy in the first levels, harder in higher levels. Oh, I couldn't resist to add a new element not in the original game: Get to level 4 and up to avoid the fog of pain. Remake of the MZ-700 classic.

Birdieparty

Colorful retro-twist on a match-3 type arcade game. No violence but full of fun!

Birdies are a strange and happy folk and loooove to party... but only with the same color. And only at least three of them. Help them finding their party and touch gangs of at least three Birdies of the same type to make them happy.

  • Without your help, eventually they will hit the ceiling - and your game ends.
  • Touching a single Birdie or one of just a pair makes her or his head ache so terribly. Also they loose their color so they really don't want to party anymore. Don't do it!
  • Touching an egg helps all Birdies of the same color to the Megaparty event. So do this!
  • Headache pills each 6.000 points to heal grey bidies.
  • NEW: Special mode for colorblind players!

No violence included, so even nice for playing together with your child (or your mom!) - but a lot of fun also just playing alone and trying to improve the Highscore.

You are good with RGB colors, really good? Here is the chance to prove it...

The task is simple: Just guess the right RGB values for given colors.
As a start, there are just two possibilities for each color channel 0 or 255 - resulting in only 8 colors you have to know. Easy, isn't it?

After a while the difficulty rises and if you master level 4 (729 different colors) and reach level 5 with its 4913 colors you're quite good and probably professionally trained.
A painter, designer, ... ?

But still, this is so far away from the 16777216 colors in level 9 - where we don't expect anyone to get anytime soon. Besides, the most mobile displays can't show these many colors anyway.

Why? Just try it and see how you get better and better...

NEW: Hexadecimal mode to make our fellow web designers happy!
