I'm gonna let the .giz file do the talking for me in terms of description, while merely highlighting the pigeonhole in the rules.
Stopping the timer using the LB2 Boss is banned in Times, but not rings or scores. The question is, since nothing is provably infinite here, should it be?
Things to note:
- Time stops early in LB2. This allows infinite time for ring attacking, as long as you know what you're doing and don't pop Sonic's only air source.
- Slope glitch is used here, but that's already allowed. See: Launch Base 2 Knuckles/Tails, Ice Cap 1 Sonic/Tails/Knuckles.
- There are two level clear screens that claim "Sonic Got Through Act 2," and both tabulate a ring and time bonus. Both are large quantities, albeit finite.
