So obviously I have submitted my game to the jam. I even changed the title slightly again (added the "Twin" word), because I can!
Anyway, the cover mechanics that I started working on during the jam looks pretty interesting, so I decided to progress further with this idea, even though the jam has already ended.
First of all, I added some more visuals to indicate that a character is hiding themselves behind a cover:
Additionally, I have fleshed out the cover system, making it more similar to the one from XCOM. Basically it does not rely on a simple line-of-sight mechanics, but also implies that a character might be able to lean to actually hit the target (which might be leaning as well):
Player on the left is able to hit the enemy even though there is no direct line-of-sight. What is more, the hit probability is 100%, as the enemy is flanked.
I guess the next thing to take care about is to make it more clear to the user what kind of cover (light/heavy) are the characters having. I will keep you posted on updates!
