Bit of a mixed feeling on this game! Overall I'm very positive on it, but I was let down by some elements of it.
In general, I found it to be very solid and charming: the graphics, animations, sound and altogether general presentation were very cute and wonderful, giving off a really professional feel. Shooting was fun and had a little bit of strategy to it with switching between the two weapons (though I did find the second weapon to maybe be a bit too weak to make it useful), and there was a nice variety of enemies to fight all with memorable patterns.
The biggest issue I had with the game were the normal combat segments. Usually a SHMUP does their best job at making these parts like a cool interactive movie, where there are all sorts of cool waves and patterns of enemies and obstacles that form a series of standout events that all create a great flow, a story of combat. This game, unfortunately, didn't have any of that. Yes, it did have some interesting enemies with unique moves to them, but all the game did was constantly recycle the same waves, over and over, even after passing the checkpoint and transitioning to a new zone: just more and more of the same. It didn't take long for those parts to get incredibly repetitive, which was unfortunate.
The boss fights were a whole different story, however. This is where the game really shined, with a very cool boss fight with fun patterns to get good at dodging around. It wasn't all perfect: I didn't like how the boss constantly 'no-sell'-ed being shot, and would've preferred them to react a bit whenever they got hurt. And more importantly, I wanted more, more boss fights! I was so bummed out that the game ended after saying 'level over' since it made me believe that it implied there were gonna be more levels! Basically, I'd love to see more of this game.
...also as a side note, I think it's SHMUP, not SCHMUP. Unless maybe that's a new acronym? Haha, anyway, it's all good.
