Yus i know about the geometry, some 2d body might need some tweaking for the collision.
For the score it is mostly base on the damage done ( solder hit by items thrown, structure destroyed manually, and a huge boost by the damage done on the final blast. If you manage to get to a place not destroyed before the end, everything around will give a huge combo)
The items in the backpack that survive the final blast would be use for upgrade... but i ran out of time for additional stages and upgrades.. this is my first jam. But i think i have a base for something ^_^
Thank you so much for the comment ^_^
