[WIP] Dodge Finger *Android*

Hi all, this is my first topic/game.
I released him some days ago, but still having some problems and doubts.

First of all the link on playstore.
https://play.google.com/store/apps/d...ol.dodgefinger

And one pick/introduction:
The objective is simple, put your finger on the white circle and try to survive.

But i am having some problems and questions:

- When the player loses, i tryed to play a sound effect, but the frame jumped to next before it plays, how can i fix it?
- I've seen a tutorial about online scores, it doens't look soo hard, but i have no idea how to implement it... Actually.
- The hit boxes are a LOT larger than the images, for example, the knife hit box still "square", theres a way to reduce it?
- What's a good resolution to use for mobile games?
- I used images for everything, because i dont know how to write text, its correct that way?
- And, what you think about the game? Good? Bad?

Ty all, i liked the engine a lot!!!
