Hey!
I enjoyed this. Cool concept and well-scoped. Having four distinct stages works well. The opening reminded me a little bit of Spore.
Going in blind, I enjoyed the evolution(s) at the end of each level & the controls were well communicated and easy to master.
The progress bar acts well as a hook and kept me going to see the next level clear cutscene and future stages.
I found the bird level a little challenging compared to the rest. Collision seemed a little sensitive!
Great job on communicating a contained story with a minimalist approach!
Look forward to your future efforts.
