I really love the checkboard patterned background, it's defintely it's own unique style. Although, I honestly would have perferred a different type of boss or custom one instead of the same wreckling ball boss that I tend to see in a majority of Sonic 1 hacks.

Thanks!

I had plans to add something more unique in boss fight, but I had limited time to polish it before publishing. Maybe if I gonna make new version in future I will add it.

Sonic the Hedgehog in Monochrome SGI

Starting the boss area without rings is cruel, but survivable :)

And... the Doom soundtrack rendition is not exactly great. Other than that, a short but perfectly enjoyable experience.

What a unique, interesting vibe here! It's simple, but a nice straightforward experience.

I like the way the checker board is articulated and used in perspective, although there is probably more you could do with it in the background (maybe it could move or something?).

Some of the music is a bit grainy, but I see and appreciate that effect you've implemented with the boss music blending in with the other BGM)

Curious to see where this project goes, as it definitely sets an atmosphere and leaves me with questions in a good way (like what's up with the statues?).

Looks cool, reminds me Sonic VR
