Only reason I'm not giving this 5 stars is cause it (The Game) ain't done cooking yet.

Had to drag myself away from the game to write this.

Played this on a Windows Laptop.

A quick TLDR on first impressions: It's really fun, lots of room for experimentation and expression with this platforming.
Easy recommend, play it, have fun, support the author/dev.

Extended thoughts: Part of me wonders if this could gain larger appeal by hiding it's more.... showy, aspects behind a patch/option. Take it from an AO to an M/PG?
This platforming feels so good, changed the default controls a bit so Mouse 1 was jump though. 
Do you the player wanna test the game for yourself?
Climb to the top of the first building, It's possible, but I won't say how.
The joy of finding out how moves can work with one another is amazing, like using Dash off a ledge, Cancel it with a ground pound, chained to another Dash to keep it going, into a jump,  GUH!

Reminds me of the fun possible in SM:O (Super Morio Odesy (Writing this while sick, not spell checking lol)).
Only thing that's been a slight downside this early on is perhaps the drabness of the environs/far off backgrounds?
Lots of empty black voids, can be a bit too fuzzy for far off environs; makes me think there should be a fog to hide the downgrading at large distance.
However, bit of a double edge with that one, if the Environs were more detailed, or there was an effect to hide it, perhaps it would distract from the platforming and affect performance?
Up to the Creators vision of course.

Voice actors for the boys are very cute too, Axyn is such a brat, I love his cheek (and his cheeks-lol).
The race against Leaf is a great opportunity to unleash all you've put together into winning the race and getting good times, and even if you haven't gotten to grips with everything by that point, just following him on a "dud" attempt is a good way to learn A way up (Since there's more than just the 1 route of course, cause this games neat like that.).

Final word for now. If you like some 3d Platforming with plenty of creativity and experimentation, cute ...uh, Bunny Bois (I have no idea what I am, but he's cute.)  and like collecting things, give this a chance.
