The concept is great, but the controls feel iffy, why not have A/D still control rotation, it'd make memorizing what the controls do a lot easier. Another way to do it is to use the mouse for drilling.
I go over the thought process for the jam version's control scheme in a reply to ronaldbabe down below somewhere. In the post-jam update, steering will be done with A/D left/right. Thanks for taking the time to comment!
