Very polished and impressively eye-catching presentation! There's a big variety of intricate ship designs and attack patterns to keep the gameplay fresh and interesting. The music matches the arcade action and tone very well. The generally fast projectiles and the graze area being mostly on the back of the ship limits the opportunities to charge up, but it still happened a couple of times each level for me. Ambush patterns are somewhat common where knowledge of what'll happen is more important than skill, but the short levels, infinite continues and generous checkpoints never made them feel unfair. The closeup art on the sides of the play area sets a nice flavor framing to the action, and it's neat to see it change as the story progresses. I don't know if you have plans to expand the game in the future, it already works quite well as a fully finished project, but getting to know more about the history, factions and characters between missions could be neat. It's a really well made game, these levels of completion and detail are incredible for just a single month of work!
