JezzBall 1.23   (details) Prime ENG   133 KB / 13 KB
ScreenshotJezzBall is an arcade-style game, written primarily in Python with a few snippets of PPL code. The objective is to fill at least 75% of the rectangular playfield by launching splitters that divide the space. Balls bounce around the area, and if a splitter comes into contact with a ball while it's extending, the splitter is destroyed and you lose a life. When a splitter successfully divides the area into two parts, the region without any balls gets filled, bringing you closer to your goal. With each new level, splitters get faster and more balls appear on the playfield—steadily raising the challenge and testing your timing and precision

ScreenshotOperate a remote-controlled bulldozer to clean up abandoned military warehouses packed with radioactive waste. A challenging puzzle game available in 8 languages! Looks similar to Sokoban but is actually fairly different. There are four kinds of objects: blue cold waste (after pushing it, it will roll until it hits a barrier), red warm waste (comes from a combination of two or more cold waste and cannot be moved), animated red critical mass waste (cold waste or warm waste can change into critical mass when it touches the critical mass), and boxes (you can push them and they will not roll).
