Great game ahah, some real addictive potential ! The sound design really added something. Especially the "YAAAAAAY" ahah. Caught me off-guard the first time xD
My only and very little criticism is that, even tho the music is really awesome, it is quite erased beside the general sound effects. Hopefully, you had an option to desactivate SFX :) ! Appreciate this kind of little details.
I was waiting for an easter egg if we try to go in space by ourself directly from the position of the spaceship ahah. Or maybe I didn't go high enough ^^
Even tho this game is about going inside the earth, the spaceship and the color used reminded me of the old "Into Space !" flash game.
Good submission !
