This character is good.. but not amazing. (At least for me.)
I don't believe Hakune does anything "new" or something that we don't currently have in the MB, but it doesn't mean it's a bad character.
It HAS effort, and you can clearly see that on the animations of the character being expressed by the taunts or the moves he does when he's fooling around.
Even with that, I seriously believe that his moveset is not a big of a deal. He's balanced for sure, having ways to get out on some places and bounce around is cool, but in return he doesn't feel risky, even with the "No Recovery" by the third wall kick. This made Hakune not very enjoyable to play on the long run to me, due to his safe nature and "okay" recovery options.
In general, if you're a new SRB2 player, or if you're a person looking for a "easy to learn" character, you may have a lot of fun with him. But if you're a person looking for some risk and adrenaline, you may not enjoy Hakune. Do give a try though, never know what surprises and revelations you may have with this character.
3/5, Try giving him a chance if you're in doubt.
