The tiles had not perfectly quadratic shapes, so they caused some bugs.
I also made a adjustment to the reverse movement check and
the recovery of the strafe move
when touching walls.
Main change is the fixed main menu
The other changes include newly added resources, like
the new ground tile and blobby animations/designs
I also experimented with the display size and camera
To adapt to the new Blobby design, the default tile size was changed
to 24x24
The jump velocity is not calculated on a one second basis anymore.
Instead the 60hz physics ticks are
the new reference for the jump force constants.
This is to unify the calculation of velocities in the blobby class.
Walljumps are now easier.
A just pressed jump event was changed to a pressed jump event.
This means the player can walljump,
with pressing a direction while sliding down a wall and keeping jump pressed.
Falling was smoothed out with a slightly and naivly improved euler method.
Also the spring is being experimented on.
