This new release improves the collision detection system. The old implementation was limited to circle-hitboxes with a maximum size of 64×64. The new system removes the size restriction and adds support for line-segment collision shapes as well as using multiple collision shapes per object. Basically it’s now possible to create lasers and very large objects.
The most important change for this version is the move to LUA for the main scripting language. The old scripting language was fast but limited. The performance overhead of LUA is larger, but the extra functionality and ease of use are worth it.
In addition to the internal engine changes, a practice mode has been added which lets you play any unlocked stage.
