- Turn menu button in hud_system (events in level_scene!) into ebitenui button
- On level loose, do not offer "next level"
- Moving obstacles don't kill the player when they hit him, they just stop there.
- use grid/collider.CheckGridCollision() for players AND
obstacles. Currenty if I use it with obstacles, the don't move
anymore when a player bumps into it, for whatever strange reasons.
Maybe add a func argument to it so that the function can respond to
the event as the entity wishes.
## Collider Rework [abandoned: see branch collider-system, fails]
