Wow! I think this is my favorite entry so far. You guys have done a great job!
Design [5/5]: The first 5/5 I've given for this jam. The design is brilliant. Throwing the needle is fun even when there are no enemies for you to hit. I love that you can keep walking around while your needle shoots out in the direction you sent it flying in. I love the enemy designs. The wizard especially is a worthy and engaging opponent to fight against. The level design is great, each battlefield offering something different. My only complaint is that in the fourth room with enemies, the game starts you immediately next to a sword guy who comes swinging at you, which felt a little unfair. Overall, well done! I'd love to see this game more polished and fleshed out.
Adherence to the Theme [5/5]: It's a twin-stick shooter with only one bullet. Nice job!
Originality [5/5]: I have never seen a combat mechanic like the needle in this game. It was a breath of fresh air.
I'd love to see you guys work more on this game. I don't know if this is the direction you're going with it, but I'd love to see puzzle-focused levels with non-lethal obstacles in addition to the combat encounters. I could see this game being a Zelda-like if you went that route. Overall, it's just so cool. Bravo!
