This game would be much better if it had two things:
1. An option to disable "always on top" and have the game run in the background.
2. The game should count any click and/or keyboard input so you can gain points while playing other games or doing other tasks. Just clicking on the actual small game window itself is not much fun when needing to click 2000 times for each pack. If this were more of a background idler I think it would be way more appealing and fun.
It's a pretty solid game though overall and if you add those 2 suggestions this game can be close to special. Good luck!
