It's a cute little 3D platformer, but it feels a bit unpolished and floaty, especially the little combat there is. However, it's heavily focused on platforming, including the last and only) boss, so that's not too big a deal.
I did enjoy that new moves like the double jump or the glide were genuinely needed to reach platforms and not a failsafe like so many other games, even if it's very easy, it's not because it's served on a platter.
Nice music and very videogamey atmosphere (it's based on different eras of gaming, so, yeah) too.
But of course, the biggest thing is that it is a completely free game.
I'd like to see where the team goes from there, they could make some fun stuff.
