Have been really enamored with this after trying the demo! I don't have access to discord right now but wanted to share my thoughts because I've been having a great time!
Also I don't have enough dev experience to speak to playability of mechanics. If I mention a mechanic it's safe to assume I'm touching on an ephemeral feeling rather than a strong opinion.
-Really love navigation being done by peggle throw. It's a neat element of chaos. It got me thinking of fun ways tosses might be included in other events on the map, like a healing campfire being more or less effective depending on how many pegs you hit.
-Crits are neat and feel really good to pull off!
-On the version I played I did notice that I couldn't fire unless my mouse was on the peg field, but I could aim higher than that by mousing around. It's extremely situational, but more than once found myself wishing I could make the shot the preview was showing but couldn't because the mouse was out of bounds.
-Something I did find myself wishing for was a chance to select more orbs to see if I couldn't have more synergy. A matryoshka ball in order to eliminate problem areas to set up a dagger feels great, but in one world there's not much time to build that way. I imagine that problem isn't there in multiple levels.
-I like that healing is a choice after each battle. It means that healing is more guaranteed by battle than anything else, so you have to put yourself in danger to crawl your way out of it. It's risky and cool.
-I don't think this is a bad thing per se, but I noticed I was very rarely concerned about removing orbs from my deck. I only noticed it because it was such a big concern in my time playing way too much monster train and slay the spire. Like I said, not bad, just a thing I noticed.
All in all having a great time can't wait to see more!
