good game i have some ideas for this! :
1-facial expresions
2- better animations
3-less smoke when you hit a enemy
4-bug fixes
5-armor
6-an craft system so you can make weapons amory and upgrades
7-maybe leveling system?
8-an "tracker" that makes an sound when youre near to a monster
9-if you make the "craft system you can make "a craft table
10-more weapons
11-voice acting
12-development log
13-custom weapons (you can make these in the "craft table)
14-diferent modes
15-graphic options
and these are my ideas but the game gonna be free? i will be waiting for an answer
