Hi, congrats on your first game. Completing it is already a huge achievement. Even more for having such a clean and cozy aesthetic like the one you did. I like how you also managed to add "juice" to where was need, making the experience of playing more enjoyable overall.
I'll list now two things that, in my humble opinion, would have the game even more enjoyable.
- Start the game with smaller gene sequences, and increase than as the game goes on;
- Give the player extra time after completing a sequence. The amount could be based on how well the previous one went.
