A fun, short incremental game, as long as you don't go for 20 lv 5 bees. I completed the tree with 1 lv 5, 4 lv 4, 4 lv 3, and 6 lv 1-3 bees (I'm writing this after I tried going for the lv 5 bees so I don't have an exact number), which is what I'm assuming the main goal is actually meant to be. Either way, I had more fun than I was expecting!
