It's okay for the Chinese New Year. Once written in a day, a man will hold the Java version for 20 seconds.

Every year, the Chinese New Year is okay. I have to write something small. This year, if it was a man who spent 20 seconds (20 seconds or 21 seconds, I forgot), it may be a little bug. I hope you can support it.
If you try hard, it can also be compressed within 100 rows, 90 rows of Tetris, 100 rows of men 20 seconds

Remaining Problems

1. Title

2. No splash at the beginning

3. Do not pause

4. Cannot start again

5. Slow speed

6. There is a conflict between the left and right keys.

7. End statistics

8. When a new bomb appeared, it was fired near the current position of the plane. Now it is fired near the center.
