Nice game. A way to look at my highscores would be nice.

Very fun!

Simple and quite fun game. The only problem I have with it is the digging controls. You should automatically dig when holding the key "down." The blocks will then break as long as you want, automatically. Overall, pretty fun game, please check out my game! http://www.ludumdare.com/compo/ludum-dare-29/?action=preview&uid=34910

Love the music, you can never go wrong with 8 bits chiptune like music ;). Agree with other comment, we should be able to dig using only the directional keys. Other than that, cool game.

Loved the music!

Pretty awesome! Music was sweet as well :)

Found it pretty entertaining although way too easy.
If a game is a bit short, there's no shame in making it more difficult. ;)

The in-game music was great. Very Sunsoft NES-esque.

I'll never get tired of saving the earth! Nice little game, wasn't that challenging though. Still had fun playing it :)

Nice game, but wished the movement of the player would be a lot more smoother ;)

I got an error though after failing:
Actor.lua:198: Attempt to use destroyed body.

Traceback

Nice work, got the same bug as mentionned before.
The music fits well

Damn. I've just seen the bug too! I will fix and re-post!

Thanks to everyone who has enjoyed the game ! it was fun making !
People werent getting their high scores loaded - and ive fixed that too
sorry you cant skip the opening text and that the movement is little rubbish sometimes
i was meant to make it so, every time you complete a level your score carries over and the timer is less and the gems are worth more - but i guess im not allowed to just add things in :[[

Unfortunately the controls are clumsy enough for me to not be able to get much O2. I like the concept overall. Nice job.

Neat little game; didn't like the drag in speed when you hit a wall and the slow acceleration back up, but it was a solid game otherwise.
