I completely agree with all of the above 😂 I basically spent all of my time on he character controller, and the second half of the jam was spent dealing with a bunch of stuff in the real world. I do like the concept though, I think I'll probably ditch the exchange mechanic in favour of something a little better like a grappling hook or similar.
Though I will say you're probably not doing very much damage if you're swapping at distance - so it'll take longer to kill the boss. Not that there's an incentive for doing it quickly 🙃
