this is an image of the rarest unlock currently in Windblown, the project 2501 skin.
Currently the chances of the skin are unknown but it has one of the lowest drop chances due to how few people have it.

unlocking the skin is no easy feat. First of all it requires you to reach the final area of the game which can be a challenge on it's own.
Once reaching the final area you'll find containers all around with very few enemies roaming free. inside these vials there can be many thing. when you break one you will be met with one of 3 things: an enemy of the area (which in this case is good), a barrage of explosives that scatter around, or nothing at all.

the aim here is to find a specific enemy either roaming free or in a capsule.
this is the target. they are a relatively easy enemy to beat as long as you stay on your toes and be ready to dodge at any moment.

Upon killing one of these enemies their is a very small chance for you to get an incrypting memory called: "Project 2501"

now any of you who have been playing for a bit should know this isn't the end and unfortunately for you there are no midway fish in this area, your only choice is to beat the final boss, but I'm here to help you get the skin so I'll help you here too the best I can.

On your way though once you have the skin you need to avoid all enemies, wouldn't want you dying without securing that skin now. That also means avoid any of these doors.
Once you reach the end you must prepare, wait for all your cooldowns and follow my steps.
First of all their is a order that you should follow when fighting the 3 bosses ahead. Left to right is what I find easiest. The green one is first on the list and quick so look for moments where they're slowed to attack, the red one goes second and it's pretty easy to blitz, the blue one comes last, his attacks are best telegraphed and he is slow however he has a really long swing combo so hang back til you know he is done attacking. The boing fish is also really useful for this fight as you can just keep bouncing on it and ruining the bosses health.

Once you have one with your skin in your pocket continue on a bit and you'll find a fish to take everything back to the arc. Thats all for this guide, I wish you all the best of luck jumpers, you'll need it.
