The first few maps were made as a practice before this level set became a real thing and were some of my earlier levels as well. The mapset will feature levels from 3 different mappers, including me and I'm aware that the original maps stand out since they were designed as standalone levels. The least I can do is make them look better, which I already started to work on and been improving on them slightly every time I puke out another version for testing, but the general idea is that the levels are much bigger and have more things to shoot at.
I'll take this criticism into account while trying to change them even more for the future release. Maps 01-16 were all made by me, starting all the way back in like 2014. It's easy to tell how much I've improved by now. I'll try to make them more unique in the future. This mapset is definitely not for everyone and will feature a lot of grind, but the best I can do is create better setpieces and maybe reduce the amount of meatshield to fight against in the earlier levels until bigger guns are introduced.
Some people like em, some don't, but maps 01-03 definitely feel dated even for me now, so thank you for pointing it out and please give the rest if the level set another try! I promise it will be worth the time unless you prefer shorter levels that are less exploration based.
