Thanks a ton for the stream and the great feedback.
I could tell it was quite a marathon, but you seemed to pick up on all the concepts pretty quickly, and found a solid quantity of hidden items as well.
I'm also glad you were able to find a couple points to critique! I've added a note to my backlog to add a "remove" binding option.
As far as the MP and TP replenishment goes, I do delay that tutorial until the first 4-party-member dungeon which is shortly after your playthrough ended (sorry for spoilers!) It felt like adding that in any earlier was prone to causing info overload given the various other systems being introduced, and Spark's basic attack command is strong enough to clear most of the initial forest area. I know some players have figured it out organically, which is great, and as a backup I'm pretty generous with Tonic and healing points in the first dungeon. I'll definitely revisit if I get more feedback along these lines though.
There is absolutely more in store with the field skill system and puzzles as a whole. Without giving too much away, I can say that using a variety of skills to overcome a single puzzle will be part of the core gameplay later on.
Thanks again!
