Scratch

It is a portation from an older one called PureBlock
Maybe this was also a clone from something. I don't know, how the original was called.

Last week I played a lot with QBlox for my mobile phone, and I wanted to have such a game also in Scratch.

4 elements supported.

- start position
- solid ground
- non solid ground
- goal

Easy to integrate maybe: block splitting. It's a trigger, if you move on it, you block will be slitt into two small blocks

ideas for ground switches, other triggers, beamers ...

Now there are 6 levels and a good test level you will see if you download it.

feel free to use some "techniques" for your own platform games
maybe sokoban, Diablo, some strategy games like age of emires or starcraft

there is a game called "Schiffbruch" (from Dirk Plate)
I think, it would be a good beginning for this kind of games.

Hope, you will enjoy it.
