This game is super addictive, lol, though it has a few key flaws that prevent it from reaching that perfect flow state of a flash game of this kind. First of all, if it actually showed you an indicator of exactly how high you got so you had a record to beat every time you died, it would've done a lot. Second of all, I found the shooting kind of annoying-- Why can't you just hold to shoot like a normal shmup? It's not like bullets have a cooldown anyway so it's just all about how fast you can mash; it makes killing enemies kind of exhausting at no real benefit.
That said, the game is still immensely charming. I love the feeling of falling allll the way down before hitting the floor. With a bit more polish this game could become a real obsession for me lol.
