19 MAR 2020:
Some days I feel like I'm not making a whole lot of progress. Then I went back and played the first demo I posted here on Itch. What a difference! It may not look like much when comparing the two screenshots above (first demo on the left, current build on the right), but the current build has far more features that can't be properly communicated in a screenshot (window resizing, sound effects, better AI, planet rotation, etc).
Today I reworked the logic for the enemy fighters. In the demo, they would just fly straight at you and that's it. Now, they constantly adjust their position relative to the player and, if they're still alive upon reaching the bottom of the screen, loop back around for another pass. Once the last few bugs here are worked out I'll be able to start on something else, something I'm eagerly looking forward to.
