I’ve already searched on several websites and forums, but I just can’t find it at all. The game is old. I think I played it around the early 2000s at the latest. It was a Super Nintendo game. There were several versions of it. At home we used to call it the “little ball game”. My memories are pretty vague. Basically, you had a cannon and shot colored balls. You needed at least 3 balls together for them to “explode”. If you took too long, you’d lose the round. But there were never any new maps or challenges. It was a single‑player game. I think that’s all the detail I can remember.
A similar game I found, thanks to Google Images, is Bubble Shooter, but it’s not exactly that one because Bubble Shooter is a mobile game. Here’s an image of it to illustrate:
