Honestly, from what I've seen this is good enough to be released as a full game as is. It just needs some more content and a few slightly more original sound and sprite assets. The fast pace seems to work really well and the combat feels crunchy and kinetic. It takes what Freedom Planet did with combat and runs much further, however it sacrifices some of the platforming which that game was built around. With this complex physics engine that allows the player to cling on the ceiling and stuff, some extra platforming challenges would work wonders. I also think that getting the player to find upgrades slowly to increase your abilities to what they are in this demo (maybe more? *wink wink* *nudge nudge*) would allow the player a much easier time in getting acquainted with all the mechanics. Overall, very solid and I can't wait to buy this one on Steam when its done.
