[coin guide] F r o n t i e r by 5ta1ker (all coins)

⚠️ This completion was edited to include all three coins in one run, which were achieved in three different completions.

It is important to note that this level was updated while I was completing it, so some aspects of the coins have changed. These changes will be specified within the guide.

Coin 1: The first coin utilizes a peculiar GD bug. To obtain it, you must first complete the level in practice mode until the end. Then, without exiting back to the menu, press restart. This will activate a bug that allows you to simply jump into the slopes by buffering the orb at 0:25 (9%), granting you the coin.

Coin 2: THIS COIN WAS AFFECTED BY 5TA1KER'S UPDATE. To obtain this coin, all I had to do was to apparently collect the fake "demon coin" at the bottom of the wave at 1:36 (39%) and play the level normally until the end. While attempting to collect this coin, I kept dying at 99%, which was apparently intentional and part of the level's gimmick. However, I was able to prevent this by playing on 60 fps. I still have no idea how to consistently collect the coin after the level's update, so I recommend simply brute-forcing it on 60 fps until you complete the level, as it's a relatively easy coin to obtain.

Coin 3: A PART OF THIS COIN WAS AFFECTED BY 5TA1KER'S UPDATE. This coin is by far the most complex of the level and took me roughly 12 hours to fully understand!

1) The first step was to collect a flower in the first wave part at 0:59 (24%) by simultaneously clicking both player 1 and player 2 (note that this will temporarily deactivate player 1, so don't be caught off guard). After 5ta1ker's update, the correct flower to hit is now randomized. It is important to note that you only have to hit the flower that is attached to the touch trigger group 950 (again, by hitting both player 1 and player 2 on top of it so you are sure to actually toggle the touch trigger), and that hitting any other flower is useless and will just mess you up by deactivating player 1 for the entirety of the level!

2) At 1:21 (33%), you will see an orb on your screen. This orb will be randomized between pink, yellow, and orange. You will have to collect this orb just by going on top of it (it is not required to click it). PLEASE note that I was never able to execute the coin with the orange orb, so I would probably reset my attempt there if I were to get it.

3) At 1:28 (35%) and 1:30 (36%), there are two longer platforms that you are able to reach. You will need to jump on both, and one of them will randomly give you a number between 1 and 8, which will be important for the coin!

4) At 2:12 (62%), you will be met with a seemingly random part of the level, which contains 9 tombstones (5 rectangles and 4 crosses). The last one is a red herring, leaving us with 8 tombstones (which, if you remember, is the maximum that the random number can give us in the previous part!) The goal is to simply double click with player 1 and player 2 on the tombstone that is the same as the number you previously got! For instance, my number was 5 and I pressed the 5th tombstone. This will activate the final part of this coin.

5) At 2:53 (93%), you will be met by two dash orbs stacked on top of each other. Simply tap twice to be in normal (not reverse) gravity. From there, it becomes a little tricky. As soon as you see the white flash at 2:56 (95%), you can see that my Y level is now -5000, which means that I am deep underground! From now on, you will need to spam, which will make you click an orb (of the color that you previously got in step 2). If you do not spam enough, your icon will be projected back above ground at Y level 200, which will then make the coin impossible, as your goal is to go under an invisible wall right before the level ends. You will have a 1.5-block gap where you will need to stop spamming (which will push your icon back above ground), in order to show up RIGHT after the final wall, but RIGHT before the end screen. It is a very tight window. If you get the "S1mple" image at the end, it means that you were either too early and died or too late and missed the coin.

Thank you so much @AutoNickGD for your help, especially when it came to finding triggers and understanding them in the editor. I really appreciate it! Gatekeeping coins shouldn't be a thing, and it makes no sense that there were no other victors for SIX MONTHS!! If you make any new discoveries, feel free to share them in the comments, and I will update the description! Good luck with these coins!
