Really impressed by the complexity given the time frame! I loved the humor, intuitive controls, and oil-visibility dynamic.
As far as constructive feedback goes, I also would like to have more visual/audio feedback when taking damage, audio feedback when the timer was getting low (not sure if this was in the game and I just couldn't hear it??? I played the browser version), and stats for how much I've upgraded the pick and attack strength (some way of keeping track of how much ore I've spent on each). I think the level and resource generation could be a bit more consistent for the first level, as well as the bug spawning (at least x amount within x squares of the player) for the first level.
Overall I thought it scaled well and I really liked the bartering system and trade off between having to leave the ship vulnerable to attack in order to get more resources. I thought the time dynamic helped the levels scale well. I wish the levels kept going! Great job overall! Fit the theme perfectly.
