Chronescher

Here's an excerpt from Chronescher's Steam description:

Ascend the roofs of the city and journey to the top of the highest tower, where you may even discover something about yourself.

Chronescher is a challenging isometric puzzle game. Set in an escherpunk world consisting of six unique biomes. It requires you to learn time- space- and mindbending mechanics in order to puzzle your way forward. As you progress further you will untangle who you are playing and what happend to them.

Master Time and Space: Learn to place portals and return to them at a whim. Place a timeanchor in order to take a snapshot of the level and restore the saved state at a later point - without moving yourself. Change your perspective in order to unveil new paths and hidden passages. The most difficult puzzles will require you to combine all these abilities and reach places that seem almost impossible to get to.
