I'm also aware of a Chrome extension called Supernova SWF player, which also may help run Flash games via a browser.

Information comes from a different game (Platform Racing 2) Information gets shared here

NG+ could be set up, but it is indeed kind of boring as setup itself involves time, however I think the idea itself is pretty neat and the result is very satisfying. Here's how I imagine NG+ Any% will work:

Start a new game, rack up progress to a point when you think it's enough (Grinding to Galiant is the most viable strategy imo). Perform the glitch and then defeat the Paladin and get to the ending screen. If NG+ 100% will be real at some point, grind to Sinjid and perform the glitch, everything else is self explanatory.

Also wow, a huge figure in Sonny speedruns has showed up, neat.

P.P.S. I have absolutely no experience in speedruns tbh -w-

An absolutely phenomenal run. I haven't thought of this strategy myself and I honestly think it is indeed quite overpowered. That also does mean that with the Saveless Slot Reload Glitch (as the Sonny wiki says) it's also possible for the player to load a save file before the Sinjid fight, so I guess a 100% glitchless is also needed.

I am very thankful for you experimenting with the glitch and proud that I could find something like this for the community. P.S. This glitch has appeared on the internet about 10 years ago (jeez) and I myself found it like 3 years ago.

A while back I thought of creating an unofficial category for the Sonny speedrunning community. Glitch%'s goal is to get to an undefined zone as quick as possible. To do this you have to die to the first stage and click reload. This works because the player never had any opporitunity to save before stage 1.
