Does the hectic aspect seem balanced? And if not, what aspects aren't? For example, enemies being too quick/slow, etc. Is the balance between using stardust for towers and using it to feed the blackhole sufficient?
The game seems too easy honestly the only trouble I had was placing the crystals into the box/blackhole
The Saturn turret when placed in a good position likely can kill any wave thrown at it
Do you have any particular ideas for towers?
An AOE slowdown tower?
A proper small range blaster tower, Possibly Jupiter launching moons at them
something to condense crystals into larger value crystals?
Does the flow of the game feel moderately smooth, and in what ways if not?
The flow is okay I enjoyed
The Ui is Grand! I like the use of circles would love to be able to use keyboard inputs for the circle such as escape to close the ring
