Good game idea I think adding a changing background would have been cool. Nicely done. 

The concept of this game is really cool! It kinda messes with my head too, Goodjob!

A nice time consuming type of game! This could definitely be something I could hype fixate on while waiting for something. My only issue is that it's quite simple, but quite fun anyways!

Very much playable, no issues at all. I've seen games similar, but not common, this has it's own style. Fun if you like to watch numbers rise, as do I!
