Sometimes its really fun to terrorise monsters a bit, and what a good experience this is! The graphics are very cute, sound design is also very nice. The game has a fairly enjoyable gameplay loop too! I played a bit till a score of 8010 and I am enjoying every second of it.
To give a bit of constructive criticism I would probably point to the fact that avoiding incoming bullets is pretty much not worth the effort, and the dodge power is never used to dodge bullets but rather used to chase monsters, which I think it's a little bit counterintuitive. The game also suffers a bit when the level goes for a while, and the difficulty seldom increases and thus feels a bit stale somewhere after 6000 points.
Nevertheless, this is a very good game and is well polished, well made. You've done a very good job making this game! Keep up the good work!
