it's an interesting concept, but
the embed is kinda screwed up
having a plain background with no environment makes it hard to see yourself moving when there aren't many enemies around you
it doesn't feel like there's a whole lot of challenge, the enemies are pretty easy to avoid even when you become larger, they're pretty slow and turn slowly enough that they can't catch up to you, while the cars (?) that drive by are pretty rare and their projectiles are slow enough to dodge easily - adding more and stronger enemy types would definitely help
overall, it's not bad though!
