As a touhou player I am all for bullet hells! So seeing one here in the jam just make me happy. The game is unique in the sense that you need to reflect certain bullets to the enemy to deal damage, which is something that was seldom seen. The controls were clean, the bullet hells were tight but fair, this is a job well done!
My only little nitpick was that the element system was rather under-utilised. The only thing it did currently was the shield thing currently, but I think it has much potentials than what we have right now. Maybe double damage, healing, bullet effects, all sort of stuff. But given that this is a jam I'd say you've already done a very good job. Well done!
