A neat little Game boy shmup that lets you jump between two layers. If you press select on the title screen, you can choose between three playable ships. This just alters where your powered up shots go though. I like that it uses a health bar instead of lives because you can take different amounts of damage, and recover health from one of the powerups. It does run into the sprite limits on the game boy though, and occasionally something important might turn invisible. It also features two anime girls so this is a must play.
I played on Medium difficulty which may have been a mistake. I found this game brutally hard and dying to a pixel perfect jump set me back a lot. The actual game is fun to play though, the movement is decent and eventually you get used to grabbing cliff edges properly. There's a lot of weapons but a lot of them feel similar to each other.
I have only played this for the first time recently and it was really stressful at certain parts. Shooting things was really satisfying and I managed to luck my way into getting the best ending on accident. I played as Chris because he's on the fucking cover of the game but all my loser friends tell me I should have picked Jill. OK.

Technically, it is a plane game where you shoot things and it is on the game boy advance. I don't think they had any goal other than that. I spent the entire game (Only 12 missions) staring at the tiny radar in the corner because you can shoot things off screen, and that seemed to be the most effective way to play.
It's too bad this is the last bump combat Ys game (from what I understand), as this was the most fleshed out and enjoyable incarnation of it. It's got cool boss battles, a couple anime cutscenes, glorious classic Falcom CD music, and now a charming fan English dub. Playing this game made me realize the SNES was obsolete earlier than I realized. It's a shame the Turbo CD didn't catch on here in the states.

I really like the challenge this game provides. It can be incredibly frustrating but it forced me to learn so many intricate details about how gen 1 mechanics work that I have to admire it. This game pulls no punches. But maybe it's easier if you import your own pokemon? I just used rentals. Either way, lots of fun.
