Not so Simple Sonic Advance 2 Worlds

General Information

nssadv2 banner.png

This is a base engine available for anyone to use to create their own Sonic Advance 2 style game in Clickteam Fusion 2.5.
You need at least Build 294.14 or higher to run this.

How to play:

['R']-Trick (In Mid-Air)

Final Update v1.2 (Hotfix) includes:
  • Insta-Shield now has invincibility frames
  • Fix Spring softlock glitch
  • Fix Homing Attack glitch
  • Simplified enemy/boss interaction code
  • Minor bug fixes

Final Update v1.2 includes:
  • Increased Acceleration
  • Fixed Tails underwater BackAir trick height
  • Adjusted air physics for Boss Act
  • Minor bug fixes
New Update v1.1 has now been released! The update includes:
  • Fixed screen resize issue.
  • Fixed lag issue.
  • There's now only one template level instead of two full acts in the source build.
  • Fixed Sonic & Amy's Underwater Bounce Height for their Down Air Action Trick.

Within the Download is the source code (Which works with Standard Fusion 2.5) and an example game built into an exe that you can play (Your PC might accuse it of it being a virus but I assure you this is not a virus.)

To turn Super Sonic press the "Select" button and you should hear a ring sfx and recieve 50 Rings if you haven't gotten that amount already. As long as you have 50 Rings after doing that jump and press "R" while in mid-air to transform.

To enable Debug mode press the "L" button in the menu you should hear a ring sfx for each time it's turned on/off which you can check in the options menu. Then press the "L" button again while in level to activate it. The "R" button is used to spawn objects, the "A" button is used to change objects and the "B" button is used to swap monitor boxes.

I have included within the download all of the required extensions you need to open the file IF YOU DON'T ALREADY HAVE THEM!

Apologies I accidentally uploaded the mfa as 2.5+. It should work with standard 2.5 now. I included a hotfix as well. There will be no more updates/hotfixes after this.
