I would really like to see traps improved and expand variety, there is so much that could be done, tripwire for spikes/arrows/falling rocks or something else cool, as others have said find things like pins or batteries or matchsticks and be able to use them as weapons/traps. Also the ability to tame more creatures (preferably good ones) e.g SPIDERS, they would be such awesome companions to help in fights and the ability to ride on them would be amazing.
Please, please, please!
