Personal Favorite Achievements of 2018: Quite a fair few for this year : finally got around playing UFO and getting 1 CCs for all shot types on Normal difficulties, finally gotten around to playing LoLK Legacy mode and getting a proper 1 CC for Sanae and Reisen, which I would consider pretty good since I haven't touched the game for what, 5 or 6 months ? And also getting my first extra clears with HSiFS and TD. But what I'm the most satisfied with is getting a Hard mode clear with HSiFS, with Marisa (Winter), which I also got after not touching the game for quite some time.
Personal Biggest Screw-ups of 2018: Doing TD's extra stage, reaching Mamizou, aaaaannnnnnd getting kicked out cuz apparently the game crashes at the end of her survival if you hadn't patched the game yet. Huh. Patching the TH games to their latest versions is not a reflex I exactly have. Apparently not getting your game to it's best version is bad, who knew
Favorite Achievements by Others of 2018: Eh. Dunno. But seeing Jaimers put a video of him finally doing LoLK's stage 6 certainly gave me a good laugh. Made my day.
Goals for 2019: Hmmm, dunno, try to get various clears and moving slowly upwards, difficluty wise ? I like to collect those "cleared" symbols. Not planning on trying score runs yet, tho. Seems a tad cumbersome.
[OPTIONAL] Challenges to Other Players: Maybe try to check out the various fangames this community has made or something ? There are quite a couple of cool fangames that aren't shmups out there, it should be worth it to try to check non-shmup fangames once in a while.
