Wanted to share some techs and bugs I found after going for P in every level. I'll update it whenever I find new stuff
You can gain a ton of speed and style by burrowing into the ground, holding jump, and releasing jump while still holding down burrow. Burrow hopping is used in pretty much every level, as it doesn't take much room to perform and builds speed the quickest (that I've found so far).
You can very easily farm bhops at the end of each level if you don't have enough by going around in a circle, doing minimum height jumps, and fastfalling (optional), but you should have most of your bhops throughout the normal level.
Currently, if you burrow halfway through a place you have to dig to get through and get stuck inside, you can enter roll mode, causing the game to think you're doing a ton of walljumps and giving you thousands of points each second. It will *probably* be patched eventually, but is an option.
The game also doesn't tell you in the tutorial, but holding down m1 causes the bun to go into tornado mode, making it fall slower and jump higher. This not only gives a ton of style points for some reason, but also lets you get about 3x the jump height, go way further horizontally, and lets you scale walls vertically, so you should really be abusing it for P ranks. You're able to "Skip" the bunny over water if going fast enough, and at a really shallow angle you can hold tornado mode to maybe get an extra bounce (or skip whole levels).
For example, on level two, if you move to the third platform and burrow hop in a circle, you'll reach the speed cap pretty quickly. At max speed, you can just jump straight to the end by entering tornado mode while leaving the ground, beating the level in <15 seconds.
My personal best times for levels
1 - 19s
2 - 14s
3 - 30s (i suck at the climbing part)
4 - 15s
5 - 19s
Sandbox - 5s
