Oh, I should've read what SimplySarcastic said first!
It was unclear on what the objective was so I kept flying a loop after figuring out the controls myself. Then flew across the entire map. Stopped playing after.
BUT it did not lag for me in the slightest in browser.
The game has potential, but the UI is unclear (I did not know what the bars on top were for) and I wish there was a better movement system. This could be a banger racing game imo.
I'm looking forward to any future updates - should there be any ♥
