It makes the HP up upgrade useless.
Also, range up should be capped since it's useless to have more than what's visible.
I just never upgrade it.
Collecting coin speed is not that usefull since later you get closer ennemies.
I greatly appreciate your feedback! I'll look into fixing the issue with close range targeted. I believe enemies are getting behind the projectile spawn point causing arrows to miss.
What if the camera zoomed out for larger ranges so you could always see the full screen?
Does the enemy speed scale too quickly? It increases with the run time until a cap is reached (2x speed). I think coin upgrade is useful once piercing is unlocked, so enemies that die further away allow you to pickup the reward quicker.
Thanks again for your feedback!
A new patch has made Pickup Speed / Range permanent meta upgrades and fixed missing enemies at point blank range. You can read the full change log in my first devlog
