Intresting concept. I really like the way you fly around and set up tiny towe defence like structures whilst moving around. (as i read this i realize i could use one of the tools to bring the planets with me). Okay, now. This game has a suprising ammount of depth. The different structures provide a suprisingly fun gameplay loop and quite a bit of tactics. The main problem comes with how the different parts of the mechanics work together.

If this was to become a complete game, i would completely restructure the way you progress and how the different abillities are presented to the player. The way they are presented are as secondary abillities. That makes it look like they are to be used in together with the primary fire. This makes the game look like a space shooter with stationary secondary abillities. I would rater make the primary fire a seperate abillity that requires 1 (green thing?). This puts focus on the abillities as the primary way you interact with the world.  Also it isn't really explained that the primary fire requires a (green thing?).  You should also restructure the tutorial to emphasize this. Add planets one can interact for example. Also give the player another goal than just getting to the top, something that give emphasis to the abillities and how you interact with the world. 

All in all its an intresting game with a lot of potentioal, but not too great execution. It has good music and some really cool and derpy cutscenes that are pretty funny to watch. The creature designs are also pretty good. Keep it up, this concept has quite a bit of potentioal.

(sorry for my maybe shabby english)

Impressive game. Great visuals and audio. I loved the planets and the bokeh background. 

I never quite mastered the strategy, so I might come back to it later.  eg: I never figured out the strategic purpose of the grappling hook.

I liked the interactive help / tutorial and you had a nice intro cutscene. However, unskippable cutscenes is a cardinal sin when your in-game help is only available at the start.

It has some easter eggs so maybe try find some
