TL;DR: NorthBoys is cheating in their run. So I rejected his run.

So recently, I received an expose message that NorthBoys is using hacks/tools to speed up the game. To comfirm this, I compared Top 4 runs in the leaderboard.

Evidence 1:decleasing speed of batteries.

• Top left: @NorthBoys
• Top right: @Bush_clover_games
• Bottom left: @1Okay
• Bottom right: @YukiCookie

Note that decreasing speed of batteries in @NorthBoys run is obviously faster than other's run. The decresing speed is fixed value, So it doesn't change unless you use tools/hacks.

Evidence 2:Speed of Staff roll.

• Top left:@NorthBoys
• Top right:@Bush_clover_games
• Bottom left:@Keima
• Bottom right:@YukiCookie

Note that speed of Ending in @NorthBoys run is also obviously faster than other's run. The speed of Ending is also fixed value, So it doesn't change unless you use tools/hacks.

Conclusion

Because of these evidence, It's very likely that @NorthBoys is cheating. This violate the game rules. Therefore, I rejected his run.
