This game was pretty fun to play! The effects of collecting points and 3D asteroids do a lot to make the game look more dynamic. Just as I was getting tired of seeing the basic enemies, larger ones start homing in on me! It was also a pleasant surprise to see enemies shooting back at me, even though they took way too many hits.
I did not notice it at first, but there appears to be a shield system in play, as it absorbs a hit and has to recharge. It adds more depth to have mechanics like that, as they are employed automatically but offer more decision making opportunities to the player.
If you do plan to add more to this game using it as a base, I would like to see power-ups that can be activated with the right mouse button. Lasers, increased shielding, you have several possibilities. I would like to see a way to add replayability to spice up multiple playthroughs as well. Maybe some form of branching paths that can be chosen by flying left or right?
I managed to get a score of 142 and the super end, and found the complete hard stop of an ending to be hilarious. Good job on this!
