First of all. This isn't a bullet hell shooter. I've seen more bullets in standard shooters. Then you add in shields and orbs/drones which can simply destroy bullets and then you've completely departed from the bullet hell genre.
Secondly the music samples are way way too short and repetitive, it gets really annoying quick. The bullet patterns are also really short and repetitive there is like 3 patterns all up.
Thirdly the game is just -way- too easy... I ended the game with 30 or so lives because grazing the lasers was a joke and they gave me a life every time I grazed them. Even without the lives the patterns weren't dense and not difficult to read... but then you also have shields/drones/pods just making it way too easy.
Ultimately the game isn't all that great, seems like the author didn't put much effort into it.
For people who can, say, beat normal on Touhou, this game should be relatively easy to get all the achievements without much effort. The game is great, I love it, but it would be even better if it had a harder difficulty mode. When you consider that your lives and bombs are recharged every (very short) stage you really need much harder danmaku patterns to made it difficult.
Nice game for people new to danmaku shooters but a bit easy for anyone who is even okay at them. Especially because it isn't a /true/ danmaku game in that you have shields and stuff. The restocking after each short stage does't help to make it any harder.
Keep up the good work though.
