Pretty fun for an early version of this game馃憣
I like that there's already a variation of enemies
Possible improvements/additions:
Controls arent what you would usually expect from this type of game (bit slower than usual)
I really miss some annoying soundeffects and music
I want to see my score and highscore when I die
A little more detail on the duck and background (but not too distracting)
Maybe some different rarities of coins (or gems) , which each give a different amount of points
Thats it for now though, keep up the good work!
