Wow, thank you so much for your time, tips and improvements!
I must admit, I did rush with the screenshots as I thought the thumbnail would do the heavy-lifting😄, I kept the "fps: 60" as some gamers appreciate this. I agree the ".Io" is possibly attracting the wrong target audience (gained 20 plays, very little stayed or rated), I was planning on adding multiplayer only after the game grows, as I will need to pay to keep the servers up. Funnily enough, many Io games actually use bots themselves so I was thinking this shouldn't be too severe.
So thank you once again, I will work on these adjustments very soon!
