Cool game overall in my opinion, very polished and professional on an esthetic point of view. Great menu, cool interface, original graphisms. The music is well wedged on the different scenes or events, and the game is smooth, fluid and without bugs. Plastically, it's undeniably a great job, and I like finding back the "old" characters I saw in your other games.
It's more on the essence of the game that I'm less convinced. First of all, I didn't see a big difference between this new game and Ooni Battle. Just adding checkpoints and a wheel of fortune (which I'm not denigrating, of course, they are good inovations :) ) is a bit too light to pretend to a sequel, when you're using the same characters, finding back the same fighting actions, the same items, etc. Actually, I liked the simplicity of the fighting and its super easy handling, but I must confess that after a while, it was even too epured and it kind of lost its interest for me.
As there are only a few options (enhance defense, attack, gain life or money), the upgrades that could motivate the player to keep playing an addictive game are insufficient here (still in my opinion). Actually, after having pick up +5, +10 or +15 attack the most I could, I just beat all my opponents in one strike (even bosses). That kind of killed the suspense. Each time, I just clicked once to attack, another to inflict heavy damages, and some other to catch up coins :) I never used items as they got pretty useless because of that...
I think it's the huge difficulty in this kind of game : to keep an addicting game addictive, and prevent the player to fell into boredom. As far as I'm concerned, I was a bit too close to the cliff...
To counter that, you included achievments (medals) and you were right ! Giving objectives is a good way to maintain addiction ;) But I'm sure you could have include some more, on streaks, on critical hits, or on the different tribes.
Though, I liked how the different tribes have their own stats, which is more enjoyable as you go through the game, and particularly their special moves. The "upgrade" button was also a good idea.
Here it is, I just gave you MY opinion on your work. I find it a good game, but I would have appreciate to see this kind of stuff in it. I hope this review helps, if you find in it some elements you agree with.
Good work, and good luck for your future games !
