Clover's Quadrants

Here is an excerpt from UDLR's Steam description:

YOU ARE WHAT YOU EAT

In UDLR, your four directions of movement correspond with four different inventory slots: Up, Down, Left, and Right. Pick up an item on your left side, and now that item's ability will be used every time you move left! This simple premise is explored in depth, with many items and mechanical surprises to discover.

UDLR is a moderately difficult game. The difficulty curve is relatively gentle and the most difficult puzzles are optional, but the main course of puzzles should still provide a challenge.

UDLR_Modify was originally created for the Acerola Jam 0 as a prototype with 20 puzzles, where it was among the most popular games submitted. UDLR is the full-length follow up to that game, keeping the best puzzles from the original while adding many more, adding new item types, and modifying some of the base mechanics.
