possibly the lamest jump i have ever seen. it's low, slow and it has a long wind up, making it useless at best and annoying at worst. also, not being able to even partially redirect the fall mid air is a deliberate choice that CAN work in some domains, but it's very restrictive and can exacerbate further the clunkyness
the controls are completely alien. j, k and q? have you ever played a third person shooter in your life?
there's a lot of effort put into the aesthetics and vibes side of things, but if the fundamental arcade loops fails then people will not stick for long. i cleared a few rooms but you should focus a lot more on the arcade feel if you want it to be fun. both movement and shooting need to be fast and reactive, don't be afraid to sacrifice realism for their sake.
