When landing on a tile, the protagonist shifts to the left. The following points were verified:
The issue does not occur on terrain with multiple tiles aligned side by side, but occurs on isolated tiles that protrude like a bump or floating tiles.
The issue does not occur when landing on objects with collision shapes of nearly the same form, but only on tiles.
The issue also occurs on slope tiles.
The protagonist shifts to the left regardless of which direction they are facing.
The bug where rubbing against a wall allows you to land mid-air also had very high reproducibility on our end, but it did not reproduce on yours. It must be that mysterious tool that works perfectly on the developer’s PC—Action Game Maker.
