AMAZING game!
The only thing was that after some time, the game felt laggy / the performance went down, maybe it's due to the fact that it's a web build. Because of that, the music sounded super weird and I had less time to react to enemies spawning.
I think it's one of the most innovative game I've ever seen in a jam, so good job!! The login mechanic is smart & the community driven progress is such a great idea.
I really loved the game! Good job :)
