Added the option to change keybindings. Please note that while this feature works as intended, the labels on the on-screen buttons and keybind explanations in the tutorial boxes will stay the same.
For technical reasons, the ability to move via vikeys (hjkl) or numpad has been removed from the default inputs.
Steps on spikes and popup tiles are no longer added to the undo queue while you are holding the feather.
Fixed a few typos.
Fixed a few level symmetry problems.
Added an option to delete savestates.
For the next update I plan to finally add achievements! From the standpoint of the game design I have a good idea on how things should work there - some standard progression achievements, a few challenge ones, and a few fun ones. I still need to figure out how to make the game talk to the Steam's achievement system, as well as prepare all the achievement images - so I am not entirely sure it will be something I will manage to finish during the next week. I will at the very least try, though.
