It's a fun versus shmup, patience is rewarded as the goal is to destroy the bigger enemies which cause an explosion an then chain-kill the smaller enemies. This will send a projectile to the enemy, which can then be sent back to you by destroying it as an "enhanced"(faster/glowy) projectile and if you send this projectile back to your opponent, it will send a special attack which is different for each character.

The more you play, the more you start noticing the same patterns.

Each stage has different models for the monsters, different songs, backgrounds, etc. The music is very good, it has high-energy vibes.

There are some slowdowns when there is a lot happening on screen, it can actually be helpful to understand what's going on as there can be a lot on the screen at once.

The AI is weird. Sometimes it will dodge everything you throw at it in stage 1 and other times it will fail in stage 5 in the first 20 seconds. Your best bet is to try and do as many chain attacks as possible and survive for as long as possible, but the CPU can move faster than you so it can dodge stuff you can't. In the end, you get the feeling it all boils down to a little bit of luck.

I recommend this one. One run is around 20-30 minutes, beating it with every character took me around 7 hours.
