This is great! Making a puzzle out of Conways Game of Life is a really cool idea and quite frankly I love everything about it!
You explained the rules really well.
The puzzles start of simple which helps the understanding of how the game works.
And the puzzles then get tougher. They expand in logical ways (more steps, bigger playing field). Also the puzzles aren't so complex that they get confusing and frustrating (at least not up until the point I played).
Regarding the presentation: The graphics are simple but very fitting, they convey the puzzle clearly and are very polished. Transisitions are cool but not distrating, the time between revealing the devlopment of the next step is fast but you still have a feeling of progression and see quickly how the field developed.
The sound effects again are simple but very well chosen. They support the gameplay without being distracting. Same goes for the music. It's funky and nice to listen to but doesn't hog attention.
I would love to tell you something that I think could be improved about this but quite frankly, I can't think of anything.
This is a 5/5 game in every category for me. And I will continue to play it.
One great thing would be if you could release it on phones because this is a perfect game for that.
Uhm... honestly if you would be willing to release this to Android but don't know how, hit me up. I'd be willing to help you with that.
