Really sorry the game has been falling behind. We fully intend to finish it, but there's only the two of us, so we were a bit drained after pushing out so much stuff in so little time. We're still thinking about the game constantly, though, so once we have some other things taken care of, we'll get some more work done on it.
We're still working on the game, it's just moving a bit slowly since we're both busy with other things in our lives. If you hit the "CREDITS" button in the game, you can visit our site, where we have a blog which is being updated as we go. I can't say for sure when the next version will be out, but it has a lot of huge changes to the game, and upgrades should be one of them.
Our plan is to make the points useful as a currency for upgrades. However, you'll also need to find artifacts (and maybe samples of alien wildlife?) in order to do research that unlocks those upgrades.
Also, lives will definitely be removed - they were just put in for this contest, since you could otherwise just get an infinite high score. In the future, you'll just lose some money and whatever items you've grabbed from the cave so far.
The plan is to have fully customizable robots, which can have different tools equipped for different jobs. Nothing is set in stone yet, since we're still working out all the details, but if you're interested in learning more about what we're working on, please follow our development log at http://www.mildlydisconcerting.com/drillboid.
Thanks for all the feedback, we'll definitely take a look at how we can improve the game based on your comments!
Drako155, The secluded rooms are actually secret rooms, which you have to dig into. They have a lot of treasure in them, though. I'm not sure what you mean by digging forever - there are limits to the level. The bug with the orb will be fixed in the next version.
Leaph, the next version will have an arrow pointing to the orb when you drop it. Sorry it got lost!
Glad to hear most of you are enjoying it!
For anybody having issues wig the tutorial, just go left a bit further to get into the ship. Sorry, we'll make that more clear later!
We'll be releasing some bugfixes in the next few days, so thanks for helping to find them!
