Setting your own spawn point could potentially be abused but adding that on maybe a potential counter could be good if the level is big enough so i'm gonna put the idea on the backburner because that sounds really interesting,
i already fixed all the stuff you mentioned, I have a checkpoint system set up but that system has been used a ton and would feel superrrr generic and i wanna lean more into the newer ideas if that makes sense :) Also i know about the cooldown thing too, it was never meant to be that long and everyone just hates the cooldowns so i already removed it in the post-jam patch i'm gonna release, plus a few brand new mechanics, i'm going to release it after the patch and to be honest i'm pretty confident people will like them but if you could give me a follow so you know when i drop it and let me know i'd appreciate that :)
