Goyouku Ibun vibes!
Well, maybe not fully but it slightly felt like that to me! Attack button influenced by direction, and dash that allows going in all directions.
The controls feel like they need a bit of polish though. The 2 attacks don't feel that different from eachother - it's also *only* 2 attacks but why do I feel like pressing Up or Down were supposed to have attacks too? When I do Up or Down + Attack, nothing comes out at all, which is mechanically inconvenient if I wanted to attack while I'm dashing upward or downward...
By the way, dashing upwards forces Shinmy to face right for some reason... Kind of a bummer.
Regarding the art assets:
I don't like this background. It's 3 contrasting and vivid colours (in different shades) and they clip into one another like a camo pattern. That high yet self-blending contrast makes it really hard to look at.
Doesn't help that this background is of similar hues and saturation to the character sprites, overall it's harder to look at the video game than necessary.
But the sprites have these Gouyoku Ibun-like animations, and the title screen has great flair. So at least the style is pleasing.
