Honestly, the more I hear about this game, the more I'm impressed that the devs are going this far for what is essentially just a Nickelodeon Platform Fighter; I wouldn't have been too surprised if they had seen this as just a simple cash-grab/easy source of money that they wouldn't need to put much effort into.
But no. Clearly, the devs do genuinely care about this game and there is a great deal of care and effort being put in to not only be fun, but also have it's own identity instead of just trying to blatantly copy Smash (which is something that Cartoon Network Punch-Time Explosion XL, much as I enjoy that game and consider it an underrated gem, is kind of guilty of). And honestly, aside from not knowing about things like any sort of shield/blocking mechanic or if there's going to be any sort of single-player mode, the only real negative I've noticed from this game is the apparent lack of voice-acting, and frankly, in light of the effort being put into almost every other aspect of the game, I think I'll survive.
What's funny is that despite not having played the game yet (for bloody obvious reasons), I already feel like I don't regret pre-ordering it in full!
And hey, fingers crossed that this game does well enough that we not only potentially get a patch with voice-acting included, but possibly even DLC.
