Got a score of 2660! I really like the initial learning curve, and I developed a strategy quickly. Power is important to upgrade, and getting blue asteroids should be prioritized. At first I was confused about not being able to replenish my health, but after my first run I realized that was a really good design choice. Normally I think of a ton of things that I would improve, but this game is pretty perfect, especially for 48 hours! The only thing I would add is some sort of indicator that you can't move without fuel or shoot without power. For example, the bars could flash when you try to do their respective actions and don't have enough fuel or power.
