Thank you for your extensive comments and evaluation!
Thanks for the feedback on the combat part, it will be one thing I will change and make better after the jam for sure.
Inventory wise there isn't really any for what you pick up except the special crystals. I made the pick ups before deciding where I wanted the game to go. At the end I decided to only use the special crystals as a mission, but decided to keep the other materials since it kinda felt rewarding just to pick them up. I hoped it would make the game more fun to keep it than to just remove them.
Also nice that you appreciated the fan art... :)
Thanks again for the comment, it sure helps!
