Having a blast so far! I'm shooting for a 1CC so I'm denying myself continues and am getting about half-way through level 4 on Normal mode. Given that I've only put ~2 hours in to it this game appears pretty easy for a shooter but I've still got two difficulty levels to unlock and get smacked by and if the game is anything like Satazius the differences in difficulty levels should be pretty extreme (Satazius has extra bosses for example). The mechanics are rock solid and the control is tight. Music is ok but nothing to write home about and the game isn't exactly overflowing with extras but you get the main game, four difficulty levels, a practice mode to refine your skills, and 3 main weapon choices along with 3 subweapon choices. If you, like me, decide to shoot for a 1CC and work your way through the ranks the game will probably give you about ~200 hours of gameplay but if you, like so many others, credit feed (you are locked in to the starting credit plus 3 extras and I'm unsure if there is a way to add more) and then plan on whining about the games length you won't have a good time but this game wasn't made for the latter anyways. Shmup fans rejoice, 7.5/10 (Rating primarily determined by fun factor with a 10 being Battle Garegga, Rayforce, or Raiden DX and a 1 being any of the Exceed games or Sol Divide)
Edit: I must not have been in the zone earlier and I was certainly out of my element playing on my 10 inch Asus T100 tablet with the docked keyboard but when I jumped on my desktop with my 360 controller in hand I dominated. Then, I further dominated when I tried the one primary weapon I had yet to test, the grenade one, which happens to be way overpowered. Now, being overpowered isn't a bad thing necessarily for two reasons: 1. I'd prefer the game to be built with one weapon in mind, the selection was actually an annoyance for me so from now on, unless I want to intentionally increase the difficulty, I'll just use my setup and not give the setup screen a second thought; and 2. these games tend to be considered very difficult so perhaps me finding the game easier will be a plus for many out there who are unfamiliar with run and guns or simply want a more accessible one. But, I still feel the edit is necessary because these changes drastically affect my estimated play time which I will attempt to update with concrete fact as I approach my 1CC's. I plan on not editing the original posted body of the review in order to maintain a standard of accuracy and provide full disclosure of any mistakes that I may have made.
Edit 2: I finished my 1CC of Normal after about two hours of play that amounted to maybe six attempts. I find that to be way too easy for my liking but I'll still move on to Hard next and give it a go. My all clear was done with the Grenade Launcher and the Missiles (whichever the middle option is) for a score of 4,738,644 which I've posted to the Community Hub.
