Mod: LF2 Timelapse (open source)

What is it?

The ultimately LF2 mod, open source and using existing and custom LF2 content
As we're in 2020 now, there's only a handful of people that actually still know LF2 exists. Since the end of times MIGHT BE coming (I'm talking about the end of LF2, which has been announced for decades), it's time we team up not as an actual project team, but simply AS THE LF2 COMMUNITY. As so, everybody is free to submit their projects.
Whether or not a submitted project will be approved for the version will depend on the decision of a group of people from the community (atm this is me and Sauce)
In LF2 Timelapse, you travel through time to save your friends and even the end of times! (stage mode)
All the original characters and custom characters play together in synchronizity, all with balanced data and AI. It's much easier to modify some of this stuff nowadays
As for the custom characters: these will be characters that have been made in the past 20-25 years (representative characters, Frozen, etc). Only those of high quality are allowed in and adjustments can be made to these characters to make the character fit their role better for the mod, to make them more versitile as a character or simply to improve overall quality. Many charachters made for mods are also very interesting and I believe we should USE EXISTING SPRITES AND DATA OF CHARACTERS AND MOVES (also from mods) SELECTIVELY. Selectively meaning: first we think of the moveset, second we decide on the resource) If you have created content and you do not want it to go into LF2 Timelapse, please post a message in this topic. We will make sure the content will be removed!
No copy/paste characters or recolors, only custom characters
As for the storyline (stage): I was thinking of having 'the resurrection of Marshall' as a catastrophic event... It's pretty cool to have the version represent members of the community, right! ^_^
Music is very powerful, and personally I find the LF2 music overwhelming. I always shut it down, just to put on music that I find fitting... Do you see where I'm going? I believe we need to replace the soundtracks with something that sphearical (not sure about credits, but I could look that up).

About legal use
Some sprites and scripts will be new, but for this mod we want to use existing materials for the most part. The reason for this is simple: creating a lot of new stuff, especially of high quality, has proven to fail more often than not with LF2 projects... So logically, we want to give credits for whoever helped, directly or maybe even 10 years ago. But: not everybody will still be around, credits will be missing, sprites and data have been copied and edited several times etc. Therefor we want to give credits where we can, but we will not always be able to. If you know more about the credits, please inform us.

So anyway, what needs to happen at this moment?

We need to get insight into credits from the start. At the moment we're hoping somebody could tell us the author of the Freeze ice punch sprites we used.
Make a list of things that have been created in the past 20 years that can be used to make a (maybe) even better version of the original game. I'm talking about everything from sprites to programming that is custom made and could be a positive addition to the original game.
Have a poll about what characters should really be in this mod (taking into consideration: %completed, quality, LF2-styled, originality)
What custom moves (on original LF2 / copy/paste / recolorred characters) made by other people in the past did you love / do you think deserve to be seen again in the mod of 2 decennia?
Hear some thoughts on the subject from you guys
