It's pretty good, even if it's a bit janky.
It's like a mix of Mega Man with a top down beat em up + rougelike mechanics. Not a big fan of Roguelikes but i enjoyed this game a lot.

The combat is a lot of fun, but it does have one big problem: The roll feels inconsistent.
It has a tendency to get stuck on enemies, it doesn't travel very far making it so some attacks hit you even if you dodge them and it has very few I-Frames.
Once i got used to it it wasn't that bad but it feels like i'm constantly playing around it's jankyness instead of mastering it.

A mechanic i really liked was the grab, it does a lot of damage, you can throw enemies against walls or other enemies to deal more damage and it can interact with the stage hazards helping you kill enemies faster. Most levels have their own gimmick to keep it fresh.

There's a few smaller annoyances like the minimap not telling you where are your items on the map, things being too expensive/getting too little money and two horrible bike levels that at least are very easy to beat.

The roguelike aspect of the mini cores can be confusing at first but it's actually super simple once you're playing. Their timed nature is a double edged sword and can make runs very volatile. A horrible run can be saved and turned into a cakewalk with the right minicores or a really good run can go to ♥♥♥♥ because your good minicores ran out of time and you're stuck with bad weapons/permanent cores. Nothing that playing well can't fix, when i had to fight the final boss i had no minicores, my permanent cores were awful and my weapon were some tier B Fists and i still managed to win.

I really hope this game gets a sequel, i want to see what happens next in the story and to see the gameplay get some polish, this game has the potential to be really amazing, it's just a few tweaks away from greatness.
