Only tried the first two levels.
Never would have guessed this game was this challenging.
It's a nice change.
The gameplay is similar to good old Streets of Rage. You can move in four direction and you have 3 buttons : Jump, Attack and Screen Cleaner
Seems like there is a lot of different enemies : not counting the bosses, I found seven different enemies in the first two levels. And not just color swap : they had different attack pattern and required a specific strategy to be beaten
While I might not be the best judge, the animation looks nice.
All I can criticize is the save mecanism : there is no auto save and you can only manually save during the VN sequence between levels. Easy to forget.
You also have to be patient to get the H animation and H scene. You have two lives. Losing one to an enemy unlock his H animations. Losing the last one unlock multiple H scenes (at least an enemy specific one and a level specific one, I think).
