AstrO2
Made in one day for the 1-Day Jam
You're stranded in deep space with a failing oxygen supply. Jump, dash, and jetpack your way through treacherous cosmic environments — dodging electric hazards, escaping black holes, and hunting for O2 canisters before your meter hits zero.
Controls
| Action | Keys |
|---|---|
| Move | A / D or Arrow Keys |
| Jump | Space, W, or Up Arrow |
| Jetpack Boost | Shift / E (hold, any direction) |
| Restart | R |
Tips
- Your oxygen drains constantly — moving, jumping, and boosting all drain it faster.
- Jetpack gives you a speed boost inside black hole fields.
- Reach the portal to advance to the next level.
- Collect O2 tanks to refuel and set a checkpoint.
