I can't lie, this is a really good game but i do have some problems with it:
Pros: I like how the bootleg style is emulated perfectly here!
I like the tight controls, it makes you more careful and precise.
The music also is perfectly emulated too.
Cons:
The physics themselves make the controls terrible at the same time, it's like you're a boulder.
The music DOES get annoying after a while, especially with that bitcrunched tune.
You also feel like you're making a lot of blind jumps mostly and that was what made me die so many times.
Also, i feel like the horror aspect is too noticeable already because the HUD couldn't have been glitched unless the cartridge was damaged or messed up.
Speaking of aspects, the window is way too zoomed in. I feel like this would have made way more sense as a GB hack than a GBA hack because a GBA hack would have at least added some more colors.
I don't really like how Sonic is mostly blue here, if that makes sense. What i mean is that every part of him is blue to his shoes from his eyes.
Also, i get this is a romhack but isn't Sonic supposed to roll? This is more of a nitpick if anything, but i don't really like how they forgot to add some of the blue blur's most famous moves.
The levels are also way too short for a "romhack" but that probably makes sense, due to the small window.
Overall, 2.5/5 stars. A decent retry on the El Pendrive creepypasta, but still manages to fall flat on it's face with it's many shortcomings.
