There should be an option to view the tutorial or not. I understood how to do all of it instantly and the tutorial is just an irritating waste of time.
Check PM. Also lowering volume slider, should mute sound, it work fine on Android. Engine I use got a Bug on WebGL in frame (without frame it work fine). But today I will release a workaround, which let user disable sound.
And there should be clicking achievements. Like 'Click 100 times, 1,000 times, 10,000 times, 100,000 times, and 1,000,000 times'. And then your achievement bonuses for them.
You need to revamp these clicking upgrades. Clicking does absolutely nothing in the long run. I'm making like 5,000,000,000 per second, and clicking is only doing a few thousand per click.
I think publishing this game on Steam would be a good idea. I think nowadays there are hardly any new people playing this game, and thus need high levels to help them with everything. If you put this game on Steam, there will be a plethora of new people in the game and will be leveling up with their fellow new players.
Well, english is not my native language. If someone would help with improving this aspect it would be great.
