Thanks for the feedback.
Yeah, there are some collision related issues, it's due to the way we decided to handle collisions to save on time.
The movement speed is a combination of us not tweaking with the numbers after finishing the core features we wanted to implement, and the fact that the player is supposed to feel a burdened with surroundings to empower the survival part of the game. (but mostly the tweaking ;) )
We might fix the issues as time goes, but I'm not sure if that's gonna happen before the voting closes.
