Hello OHTHEFROG , nice to meet you!.
Thanks for reviewing our game. It definitely helps improve it.
The game doesn't require a login because it doesn't have persistence. Still, I'm trying to fix all the bugs and issues between the client and server before adding that feature.
So I'm preparing a new version that I hope will address your concerns. The new version includes a new system that allows you to avoid going through the terrain.
Let me know what you think. I hope to see more reviews from you in the future!
Thanks!:
