We are using a Asset from the Asset Store we bought a year ago, but we wont make Advertisment or Name it, for certain amount of Reasons. It has a whole Character Creation System with Inventory System behind including the Chibi Characters, with a few tweaks we changed it for our needs of Warrior Vania.
The Quickswap for Weapons as well as Potions, we already discussed and definitely planning on implementing it. I think that's the issue everyone is pointing out so far, that it is quite uncomfortable to switch between Weapon and Resource Gathering Items. I have to say it myself after playing it for a long time. While in a Short Play its okay, for longer sessions it gets frustrating.
For the Enemies, mhh there are 2 Attacks, Direct Attack and then Collision, as example Monsters without Weapons deals direct Damage to the Player once they get in Range, while Characters that carry a Weapon have Colliders on it which Trigger on Hit which can cause or look like they have a big range. I think balancing it is a major Part of everything and to be honest we hadn't much time on Balancing everything out.
Thanks for the Feedback, and im happy that people see the "Zelda - Metroid" combination.
