Fly the mission first, then build your own. Place enemy waves that fly straight, zigzag or chase, add shield, rapid-fire and health power-ups, and choose the colours of your ship and enemies. Every level can be played the moment it is built.
Needs a keyboard: use a laptop or desktop computer. Your game is kept in this browser; a free pupil account (just a username) saves it and lets your child share it with their class.
How to make your game
- 1Play the mission: arrow keys or W, A, S, D to fly; your ship fires by itself.
- 2Open Build and place enemy waves and power-ups in each level.
- 3Play your level, then make it harder or fairer and play it again.
What your child practises
- Designing a level, testing it and fixing what does not work
- Balancing difficulty: how many enemies, how fast, which power-ups
- Thinking about what makes a game fun for someone else to play
A tip for parents and teachers
Ask your child to build one level that is easy and one that is hard, then explain what they changed. Saying why a level feels harder is the heart of game design.
