Nice game, look the ones for android and ios

Quite enjoyable.

Yeah, I liked it and it runs smoothly. If you were looking to develop it further you could:

Create levels with goals, get a certain amount of points to advance, with a limited amount of arrows.

Add power-ups (extra arrows, bonus multipliers, larger balloons, scatter shots etc).

Add different types of balloons good/bad (power up balloons and extra time balloons, opposed to, slow down balloons, time/point reduction balloons).

You could also add a penalty/bonus for accuracy ((number of hits/number of arrows fired)*100)) 5 hits/10 arrows would be 50%[halved] score whereas 10 hits/5 arrows would be 200%[doubled] score giving a larger incentive to be more accurate.

Well this is a liltle bad and the music is horrible

very addicting and if there wasn't a time limit i would have played for a much longer duration. the music doesn't fit the game at all but at least there's music. speed at which the balloons rise could definitely be faster since at the current rate it presents no challenge.
