I created a simple TAS engine for eddynardo's current series of games, initially aiming to TAS "Sticky Sorcerer" (see: https://www.speedrun.com/Sticky_Sorcerer/thread/hwkw6 ). Today, I finished a TAS for Choppy Orc that improves @Neinet 's excellent RTA record by just under 10 seconds, reading 114.752 on the end screen. I worked carefully to plan and optimize each level and would be very surprised if so much as another half-second could be taken off the run.
I hope you enjoy: https://vimeo.com/310082708 . Gametime passes very slightly slower than normal in my replay but the in-game timer can nevertheless be trusted.
My most significant save is on level 14, where the TAS executes 4 frame-perfect jumps off the edges of deadly surfaces to save about 5 seconds over the strategy used on the leaderboards, but the TAS's optimized movement and "double-jump" tricks over the preceding 13 levels would still be a bit more than enough to push @Neinet or @LazyTitan below the 2 minute mark. I have no idea whether this goal is within human ability.
I'd be happy to answer any questions or send my tool, in the form of a patch to the game's JavaScript source, to any interested parties.
Amazing! The level 14 jumps are an inspiration to see, and the rest of the levels' optimizations are nice to see put into practice!
