I didn't quite get it. After trying to hold space, nothing happened. After trying to repeatedly press space, it barely moved and then exploded shortly after leaving the ground.

Didn't quite get the point, but it was fan to fall down and crash. :)

I think I killed my space bar... just kidding. I killed a keyboard some 15 years ago playing Tekken or something on PC. This game wasn't that bad in button mahsing ;).
Unfortunately there isn't that much to do. I guess there is some subtext with the Hangul and the red rocket...

In fact you only need to do a jackhammer on the first screen, you can hold space afterwards. Please don't kill any more innocent space bars :-)

:( My poor spacebar

I succeeded in lauching my rocket.

Interesting idea, but had to quit in order to save my space bar. Also, looks like it isn't loading your music properly.

The red button, space rocket version. Head hurts...

Launched a rocket, read some text, then saw some gibberish on the screen. Gave up and crashed. All in a days work.

Managed to get it in the air and then floated through some screens with description but didn't really get what to do from there on.

Eventually holding space worked for me. At the end I saw a bunch of gibberish text which didn't change, and I kept falling but the text never reverted. I guess I won?

mashed the space button till i was tired of mashing space button, couldn't figure it out.
