First ever 1:50, and the last ever second barrier! (although 1:49.347 is possible with l+r) Improved over me and matymaks ftwr with an extra framerule in 1-3, by adding a fast accel and just doing super clean movement. you dont necessarily need a fast accel but i find it easier personally. 1-4 wasnt amazing in this run so you can definitely improve it (it was 3 frames slower than the ftwr). you can also save a framerule in 1-1, but thats just crazy. fast accel at the start, insane underground, fast accel + ffa out of the pipe and an insane mushroom block hit and flag despawn, which ive never done in practice but ive barely segmented it, and wont be in the record for a while. certainly no record contender is gonna get .4 with it, unless someone like niftski goes for it, which he could definitely get cuz hes cracked. played on nestopia.
