Is there a maximum amount of arrows? I'm up to shooting 12 at a time but it's difficult to count because they disappear so quickly, I have to shoot and pause the game but let them fly far enough that the menu doesn't block the arrows so I can see them to count. Wish the shop told you the maximum, like 12 out of XX number....

Is there no end? I reached level 21 and noticed there was no new type of enemy after level 14 onward. It just keeps on repeating the same enemies but with more number every wave.

Anyone know what the highest lvl achieved is?

Any chance of adding MP down the road so I can enjoy the game with my mother?

Is there a way to speed up the timer? Any button or something?
