The graphics and the UIs are top notch, really liked them and the sound is also on point. The gameplay is a bit too linear in my opinion, and this is made a bit worse by the fact that the waves are quite long right from the start. The game does not really incentivize moving at all (a problem that can be found in my game too), in fact I managed to pass all the waves just by standing still and shooting from the middle of the screen. It would be great if the asteroids rotated around the planet: that (other than admittedly making programming the enemy AI much more difficult) would make the game more dynamic.
There's room for improvement but it's a solid base, good job!
P.S: I found a bug with the shop: I bought directly the third ship, without buying the second one first, but I could use only the first one.

we planed to have something like the moving items but because of a limitization with Nav2d mesh were were not able too do so (which our enemy relies on).
Thanks for noting the bug, you should be able you use the third ship even if the second is not bought so some signal may be not connecting correctly.
