Overall a fresh and interesting game!
Would really like if the movement was keyboard-based (though it might make the game too easy).
Also would be very good to add an option to sell/remove upgrades - could be painful if you upgrade the enemy too much and cannot maintain your dodge streak anymore. Also could potentially add a Pause button that stops everything on game screen - some upgrades like Money Multiplier have a low cost scaling, and it is really not great to lose the dodge streak and the multiplier that comes with it because you were busy upgrading the multiplier.
Like that you added an option to produce money passively down the line.
Just a couple of minor display bugs:
- Bullet Turret Count upgrade says that it will add 0.25 turrets on upgrade - of course, it actually adds one.
- Beam Turret upgrade strength displays the Deflector upgrade strength instead.
- Nudge Delay upgrade says it will add 0.1 to the delay, of course it actually reduces it.
