You have the foundations, but so far there is not much game to it. Also, when ascending you have the option to click "Continue Run" but then you're stuck and can never ascend.
For continued development I suggest doing something different than the millions of styles of this genre already and present choices, maybe you have to choose between upgrades instead of having access to them all.
I also suggest letting people hold down the mouse button instead of clicking to reduce peoples risk of developing carpal tunnel. People can just use an auto clicker anyway.
The design is pretty and on theme. Nice work.
