The game is not long nor that hard, it can take less than an hour to beat depending on how good you are.
The gore is good and sprite death animations are enjoyable. The problem is that to unlock the CG you need to give up and restart the level. This is a horrible gameplay decision, since I don't want to repeat the same levels 7 times just to see the death animation with each new enemy. This alone can make the game drop to 1 star, but someone shared here how to modify your save file to see all the CGs. It still not a perfect fix since now the sprite death animation and the payoff CG are in different sections, so you don't get the best experience. It's quite a disappointment, really.
This makes the optimal way to play to actually try to beat the game like a tryhard without trying to enjoy what the game offers.
Example: I'm in the stage 3-3 and I get killed by an enemy. I see a nice sprite animation and I like to see the final CG with the horrible consequences for the protagonist. But if I do that I will need to start from 3-1, so I don't get to see the CG so I can restart from 3-3.
And even after beating the game, if you what to see a boss CG you need to reach the end of the level (you can't choose the boss stage, so if you want to see the boss of Stage 3 CG, you need to complete Stages 3-1 to 3-3), let the boss kill you with the attack you want to see. If the boss has more than one attack with a CG you will need to do this again. I think some bosses have 3 CGs... It's a complete chore.
Other than this, the game can be a little frustrating, so I can't really recommend this.
