I created two new ones a few days ago.
Just a Drop: A minimalist map.
Oscillation: Two cubes, some lasers, and a track platform.
EDIT: Third one:
Trap Door: This one is rather unorthodox. You will need to use a certain glitch.
And a few previous ones that I don't think I have posted yet:
(Cooperative) Objective: You need cooperation and wits. This is my favourite.
The Orientor: It's simple. Just do what you have to do. There is a simple solution and a difficult one.
Unpoignant Drop Combo: Three successively more difficult fling challenges in one.
Blue Lore: Another minimalist puzzle.
(Cooperative) Synchronized Flinging: Like most of my puzzles, this one does not involve difficult maneuvers, but it is very difficult to solve, because the players essentially must think as one.
In one or more of the maps involving out-of-box thinking, I try to train the player with the concepts involved in the map with easy puzzles before going forward with the hard puzzles.
If you try solving my puzzles, I would appreciate demo files / video recordings of your progress from begin to end!
