Sonic Magnified

By Giovanni

Sonic Magnified is a demo of a ROM Hack of the original Sonic the Hedgehog. Powered by Sonic 3 & Knuckles' Object and Ring Managers, this ROM hack is capable of containing levels far larger than what you're used to seeing in Sonic 1!

In addition to that, this ROM hack introduces a new move: the Spring Dash!

The Spring Dash is a move you perform after bouncing off a spring. You perform it by pressing any direction on the D pad while holding A, B or C.

Depending on which direction you pressed, you may perform either of these:

Upwards Spring Dash: Need a push to reach another section? Need to perform a bit of precise platforming? This move will propel you upwards while canceling any horizontal momentum.

Side Spring Dash: Great for a quick boost in speed! This move will cancel all vertical momentum.

Downwards Spring Dash: Need to make a quick landing? Use this move! Also, if you destroy a badnik or a monitor on your way down, you get to perform the...

Spring Dash Chain: That's right! Destroying badniks or monitors with a Downwards Spring Dash will allow you to perform another Spring Dash! But be careful: you'll be rendered completely vulnerable until you perform a new Spring Dash!

The Spring Dash, the Spin Dash and the many quality of life improvements made to Sonic's arsenal will provide you the perfect moves to traverse the levels featured in this ROM hack.

This demo features one act of Green Hill Zone for you to explore to your heart's content as you listen to a custom remix of Green Hill Zone.

Look forward for future updates, as I "magnify" this game even further!

Beware! There is a glitch I forgot to fix in the current version of Sonic Magnified. If you take the middle route after the last checkpoint, do NOT backtrack after traversing the quarterloop! Sonic will be killed by the level's lower boundary. I deeply applogize for this inconvenience, and will fix this issue in the next release. (For reference, the route you are most likely going to take after the final checkpoint is the bottom route.)
