We got 2 new crazy updates pretty much right next to each other, with plenty of game modes that are viable to actually finish, but the biggest change is the fact you can pick your speed for any game mode you choose to play.

This means every existing game mode has a "fast"/"rabbit" version to it. Getting all apples is usually enough of a challenge by itself, but doing it while the snake is fast and you're likely to make mistakes - is just THAT much harder. Any mistake is costly, where one single mistake can end the run instantly with a death.

So the way I run fast mode when going for all apples is by using the coined "low coil risk" strategy, during the end game.
It's quite simple, I alternate being going vertically and horizontally and "split" the board into 4 sections. Sections length vary according to what I feel like, but they are between 5-9 blocks long.
"Coiling" with 3 or 2 is considered very risky in my opinion and this strategy avoids that.
The "free spot" in my strategy remains in the middle usually, if the apple spawns there (worst case) it's not that hard to get it safely, which is another bonus. In multi mode, you could just leave it there and eat the other two in hopes of reaching it by the end.

Here are two runs where this is used: https://www.speedrun.com/snake_game/run/zpr0pqvm https://www.speedrun.com/snake_game/run/yv6kd16z

The reason I do this strategy isn't because I'm incapable of coiling risky and get it done, but rather because I don't want to lose runs to making that kind of mistake. If you want to complete an all apples fast run - getting as many attempts in as you can is a good idea. If you spend 10 minutes just to die on a risky coil, it's quite frustrating.

This is why I recommend my strategy, it's very easy to pull off and if you make a mistake such as turning too early, it'll likely be fixed by your next loop around the board. The other thing about risky coils is that they require more focus and work, so my strategy is just that much easier.

Really I don't have much to say about this, that's just my opinion anyway, good luck out there :)
