I played until Adaptation Level 2. I enjoyed getting the achievements, and the milestones. I understood onboarding and the game pretty well. However, the adaptations did not give enough to justify reseting everything.
I quit because the game was becoming slow. In most incremental I play, after reseting, you can get boosts that bring you back to the same progress within 1 - 10 minutes. I didn't get to the skill tree, which was my goal. I agree with the 5th paragraph of Dragon Isles comment:
The thing I least like is starting over after each level/training cycle. It felt like I was only just making progress and then everything reset.
The terrain and animations were nice and helped me invest more time.
One question, is this meant to be a idle game, where some parts might have you leave for several hours to get enough progress. I didn't try that, nor offline progress.
Good for the prototype though.
