I ain't gonna sugarcoat it: It's not amazing. BUT, however, it does it's job well.
Let's get all the bad stuff out first. The sprites. Mainly the doll ones. Not exactly the greatest or most fitting, but hey. They creeped me out a tad, so it did what it set out to do.
Second, the random boss fight. It's just GFZ3 Eggman, so not great.
And it was also a little on the short side, the true "scares", I'll say.
Now for the good stuff.
The level design is AMAZING! It creates a creepy aura and a sense of not being safe while still being "realistic". And the body was an AMAZING touch!
And the textures are GREAT. Love it, mwah. No complaints!
Overall, it did what it was supposed to, VERY WELL, may I add, but it made me feel like I wasn't playing SRB2 anymore.
