Good balance between story and gameplay. The story was compelling enough to make me play it multiple times (before the crash was fixed) to see it through to the end. I liked the various changes that occurred as time passed - that was a neat touch, and helped sell the narrative impact of time passing despite not much time passing for the player. Overall 3D aesthetic/gameplay works well, and is a nice change from the usual 2D shmups.
Two small bits of feedback regarding the gameplay:
- Getting hit near the end of a level and being sent back to the start felt punishing. Having even just one spare life would have helped a lot with this.
- When hugging the bottom of the screen, I'd occasionally get hit from behind from an enemy that already passed me. Eventually learned to not hug the edge of the screen, but it felt pretty bad.
