I personally don't like level 7. There's this one single platform skip that's barely possible, and sometimes I miss it, which kills my run.
I find that most of my run killers are at the first 5 levels because I try to optimize them too much. Also, 27 and 29 ruined a deathless all levels run I had a few days ago.
Right now 10, because I never really learned to play it skipless since the skip was so easy, and I haven't learned the new skip yet.
29 because jumps are hard to pull off when i go to quick (but if i take time i can because i have beaten it before on impossible version)
game update!!! load times are gone. yippee!! so a lot of runs will get faster and stuff
also, the in game time setting will (probably) be removed from the time settings thing because we dont use it and its a huge inconvenience for mods happy update !
