Since this game relies on running the same tiles over and over in consecutive loops, you want to ensure that your hero is stepping on the same tiles as often as possible, sometimes even at the detriment of back-tracking.
Intuitive and Efficient Set-ups
You may be inclined to have your starting loop lay-out look like this, but it is incredible inefficient for leveling your tiles as your loops progress. This pathing has 8 commands.
This path hits the exact same landmarks and costs 10 commands, 2 more than previously. You have the upside of double-dipping the T-intersection tiles to get double exp per loop.
Excessive Interactions, Extra Exp
Thanks to Yoshi, M.D. for his great guide, all credit to his effort. you can also read the original guide from Steam Community. enjoy the game.
