Hyperactive is right for this game: once you get going and get used to how fast the game moves, it feels incredible! I loved both the battle sections and the platforming sections and how they seamlessly worked together: the feeling of flow and speed was incredible. Battles were awesome: I loved how chunky the hits felt and the great way enemies flew and bounced around, and I like the way you could just mash attacks and directions all over the place for great combos, but you can always instantly cancel with a dash to dodge an attack. Just has a great sense of freedom to it!
I do have a few critiques though (minor things, haha, overall it was great!) When wall-running, sometimes I would find myself hitting jump near the top of the wall, hoping it would jump me upwards onto the ledge to finish my run up it, but instead it always jumps me backwards away off the wall: it's ok, but it might be neat if you could influence how you wall jump with directional keys for better control and flow. Pressing a button to rapidly finish a line of dialogue would cause you to need to press two more times to go to the next line of dialogue, instead of just pressing once more. Freezing the camera for slow-mo after a dodge can be a neat effect, but it can end up confusing with me losing my character by running off-screen. Animations for some of the player attacks felt a bit slow with too many frames of blur: could stand for less blur frames or just reducing the amount of time between frames. There were some weird graphical glitches at times, like some weird screenshake and lines appearing at the top of the screen. Also in general, sometimes the game just felt a bit too loose and zippy for its own good and it made it tricky to control or tell where hitboxes were and such, but I think I got used to it.
All in all, looking forward to more from this!
