This collection includes three games, but only two have associated achievements. William and Sly 1 and 2 are 2D platformer collectathons. The Everloom is a top down pixel art adventure with no related achievements.

William and Sly 1 maps
Use the 100% Speedrun Route map (third on the page; probably easier zoomed in on a second screen). (I found some of the Q# instructions to be off by one; follow the color indications. May be more difficult if you are colorblind.)
For 35k score, finishing quickly is very important; if you're fast enough, you can miss one or two darklings and a few mushrooms. If you miss the target score (which is likely if you're trying on your first attempt), it may save time to continue the save to clean up any missed items for 100% first. Getting all darklings in one run is not required for any achievement, but getting 5 is technically missable. The boss has a consistent pattern which you will want to know. Turning off the rain is a menu option.

William and Sly 2 is a lot easier, no speedrun required, and gives you items later on to find whatever you're missing easily. Using a guide/map may speed it up a little.

There is a basic
guide to both games with tips and links to video speedruns. As far as I know the gameplay is mostly unchanged from the originals, so guides other than those on Steam should still apply. For example, JayIsGames guides linked here.

If you do a blind playthrough of both games and use the guides for cleanup, expect closer to 3.5+ hours. The Everloom will take about 40 minutes to complete without a guide.
