Many thanks for taking the time to play! Really glad you had fun.
The crafting was a fairly late addition to stay neatly within the fusion rules. To me it only really feels needed on Masochist difficulty, as I tended to move through things a little too quickly to get value out of it. Crafting lower rarity gear would have been a really nice addition. What difficulty did you play on in the end?
You are the first person I've seen to fully engage with the crafting almost as a primary mechanic which is really interesting, it seems many of the other players almost completely neglected it.
You are not the first person to mention WASD working in the menus however, so i'll certainly look to improve one-handed gameplay for future jams ;).
Thank you for getting around to this, really appreciate your excellent feedback.
