Game always throws you back into tutorial which was annoying but other than that gameplay was alright. I didn't enjoy this game as much as I thought I would because as I progress I just feel weaker. For me I'd love temporary power ups to drop in addition to relics like a shield or rapid fire x3. Also it was hard to upgrade my energy because if I stopped moving I would get hit. They should add an auto upgrade option. I know that there is an increased fire rate thing when the energy is full but the option would be helpful.
