Oh, I really like that title entrance animation, where that Eggman installs a bomb on the timer, blasts Sonic away, and then enters the level. I love this design.

Me too

Amazing showcase of programming! That intro cutscene was really nice and entertaining, the stage is very vast and big and i really like the music too (that scrap brain motif was so genious i have to admit

I really hope to see this one get completed! It has extreme amounts of potential.

I went in expecting an amazing experience for the short demo this was and i cannot believe how much i was let down. This game looks pretty and the music is top notch. But i was not satisfied with the level design it plays like a mario game with a sonic coat of paint and i really dont like that. Theres only so much a pretty game can look instead of playing good. The game starts off so great but then it just dips down insanely low. I see potential with this hack in the future but, as of now it just eye candy.

I love the idea making prequel of sonic 1 with prototype elements (yeah, yeah it's conceptually reminiscent of Overture but i don't think Katsushimi inspired by this project).

And i love the intro animation, level art and other

just as i saw the story description,(especialy the bonus one under the story one),it rly tells smth,that no one cant give up,neither me,u and all of us (during rom devlogs and progress)

i must say that its rly a good message u did...

I will say this defintely shows alot of promise! The level design was a little bit confusing towards the end of the second for me. Although I admire the art and music direction!

Loved It, from the cutscenes to how It feels, great visuals

There are fundamental game design issues.

The game was composed of mostly vertical platforming areas (mostly in weird interior areas) which was hard to focus on where to go. The only gimmick was a ball puzzle that felt clunky, not fleshed out & poorly telegraphed for novices. The later half just focused entirely on plain platforming + needing springs to go up areas.

Judging this as a fan rom hack, it’s decent quality. But having good art work and technical qualities doesn't save poor game design.

Thank you all so much for the criticism so far!

Bluntly, this demo isn't the demo I wanted to ship for SHC. High Hazard is outright unfinished, It lacks a core gimmick and doesn't really have a pay off for the exploration elements we designed around. We really rushed this demo for SHC because we wanted to sell the concept, so it's less a full demo and more a proof-of-concept. Regardless of this, I'm glad so many enjoyed this hack!

Visually, this hack is a marvel, both in level design, sound, and especially in the graphics. The pixel art is truly precise. Even though it's a demo, it has huge potential. I hope it thrives.

By the way, will SEGA MARK V be compatible with the latest Mega Drive? Will it have sprite rotation and deformation effects? It would be crazy and the next level of ROM hacks.

That screen is referring to the R&D group that calls themselves Mark-V, not the enhanced MD emulator included in the Mini consoles.

I think so too

This was a neat proof of concept! The presentation is top notch and art is stellar, although I found that the figments were often difficult to see. The level design is interesting, but I wish there was a secondary task or incentive for looking around and platforming in "out of the way", other than rings (I'm assuming this is going to be implemented later?). Can't wait to see where this goes in the future!

You made your own Sega Mark V splash screen? Impressive!

There is it, your "short and sweet" hack of this SHC :) Fantastic presentation, gorgeous art, a pretty good remix of SYZ theme, the moveset is limited but on theme for "early Sonic", and while the layouts can be a bit confusing at times, they're perfectly playable and a solid foundation for more to come.

Did had a bit of trouble getting this to boot on BlastEm (the latest nightly, freshly built) for whatever reason, took me a few tries but eventually got there.

This is definitely my favorite hack from SHC so far!

I really liked the art and the intro, the level design is definitely different from what you would expect from a romhack or 2D Sonic game, but I didn't mind at all. I mostly prefer to go on a lower pace or explore when playing Sonic games/hacks, so this was perfect for me! I also really like that it tries to remain simple too.

I am definitely following this project, good job to everyone who worked on this hack, and I hope it succeeds in future releases!

There's clearly the germ of a good idea, I think that it should be improved

The levels did feel quite empty, but also somewhat crowded by the foreground

While there were sections you could earn quite a bit of speed, I feel like for the first level, some of the platforming sections could be toned down a bit

There should be more enemies and spikes around the levels

The level length is actually good, it just needs more substance throughout

In short, it's not bad, it just is a bit empty

Man, I'm a sucker for funny cutscenes in Sonic hacks.

Even though this is a short demo game, it doesn't really disappoint. I like the character and level designs and would love to see how far this game will progress. This is the first game out of the contest that I have tried out and have uploaded my playthrough video with my thoughts on YT here.

Oh, I guess this is the best ROM Hack ever from 2025. Liked when they made a cleanup and the file size is minor, like when you produce new projects and build it.
