Thanks for the excellent and very detailed suggestions!
We are considering a sprint meter and health bars for demons. This could be revealed or hidden according to player's choice.
I agree, the items being demolished by the houses is pretty unforgiving.
Stockpiling meat is a challenge until you get the carrying bags.
The demon words not appearing is a bug in the latest build - before, the words would disappear quickly after being selected. Now they persist until summoning is complete. Somehow this is causing frequent delays
I agree, the red trolls need a lower chasing/aggro radius, or a limit to the max distance they will wander from the player. They tend to chase across the whole map ruining any stealth advantage.
The sleep mechanic definitely needs to be improved & streamlined. We're planning to lower sleep time for smaller demons, and possibly create a new resource to replenish their sleep instantly. Like a cup of coffee.
We're considering more strategic abilities for the player - currently experimenting with a lasso. Also considering a knock down ability, by jumping onto villagers with springy boots.
We completely agree about a demon leveling system! This will be a challenging but exciting addition, likely in the works soon. Can make the demons grow gradually in size and possibly "evolve" at certain stages.
