Really enjoyed this one!! Love main wand concept. It's an excellent addition to the survivors genre, especially as a fan of The Binding of Isaac and Noita. The enemy waves also felt 'fair', not too easy, not too hard.
I didn't fully understand the Mana concept, my mana would get larger and larger even if I dropped my spells and went for a more simple wand setup, so every now and then my wand would stop firing for a very long period of time until it recharged the entire large mana number which didn't feel right.
The control scheme didn't feel very natural, no need to reinvent the wheel in this department. Arrow Keys + ZXC or WASD + Shift Control Space would have helped.
All in all an extremely promising concept, worthy of being developed for a full release.
