Good fun incremental game. There is definitely room for growth too, maybe a prestige system.
The archer could put his new-found skills to fighting things that bite back. The magician must get pretty bored generating targets all day, maybe he could have a side hustle selling used arrows or something to generate more income.
And something that was possibly accidentally overlooked is that the last two talents - Afterimage and Higher Dimension - are the only two skills that don't come with a level number.
One last thing that may benefit people like me who have a dinosaur of a PC, is the ability to turn off all the arrows. I know they are there and although it may defeat the purpose to have a game about shooting arrows with no arrows, it would maybe speed up my game and make it possible to max out everything before my PC explodes.
EDIT: I just had an idea as I see my archer stop shooting every few seconds as he destroys all the targets around the same time and needs to wait for a new one to generate.
Maybe a second column of targets could be added that could be hit when there are no others to get.
On top of that there could be a pierce ability where arrows have a chance to go through the first target and hit the second, albeit with reduced power.
Then again, this reduced power could be increased with another skill.
Oh, I'm sure that I and all the other players could come up with new ideas all day long, but I'll leave you to do what you've begun so brilliantly :)
