Finally completed game4 which is collect the balloons, first I was very frustrated as none of the code was working and balloons were not being able to be collected, then I remember that I had my game one which was a platformer game in which we have to collect hearts, so I duplicated that minigame and codes, changed heart to balloons, removed extra platforms, added text and counters, change some code to make balloons fall, and wrote code for counters, now it is finally working! you can see in the image, the small text and number which are counter, one is for counting the number of balloons caught and one is for counting the number of balloons remain, ahh I forgot to tell the target is 4 balloons to collect under 7 seconds. good luck!
