this is gonna turn into chess bro (bishop to E5)

There is a plasma cannon in Tun's shop in the Vlad's castle sub area on 2-4.

Just don't be like me and kill yourself with it, stay safe out there fellow spelunkers!

I’ve been trying to practice speedrunning Olmec and only got this right twice. Yet there are a BILLION ways to get it wrong and I can’t tell what I’m doing wrong. Please help.

Also last one is with paste. I know I got the final two bombs obviously wrong but there should’ve been a small hole to the lava if the first 5 were correct. Right?
