Version 0.4.1

The level editor grows from a timeline and a hierarchy into a full editor, and levels get post-processing, audio effects and repeatable randomness

Editor

An inspector for objects, keys and level events. Before this version the editor had a timeline, a hierarchy and little else
Five timelines: the level, the keys of one selected object, level events, audio and prefabs
Gizmos in the viewport for position, rotation, scale, size, anchors and pivot. Each mode has its own keyboard shortcut
Prefabs were reworked: a template is edited in its own prefab mode, and each placement can override values of the template
Level resources are managed from the editor: audio, textures, fonts, colliders, effects, themes and prefabs. Effects, themes, colliders and prefabs also come from ready-made libraries. The file picker works on desktop only for now
An editor for your own colliders, a curve editor, a gradient editor and ease presets with a preview
An object can change its type and its parent without being recreated
The selection is drawn as a moving dashed outline
The level can be played straight from the editor. The avatar is visible in the editor, and post-processing can be turned off there
Level settings got authors, licences, generators and a rules check that finds problems in the level and offers to fix them

Post-processing as level events, 12 of them: analog glitch, digital glitch, bloom, chromatic aberration, colour curves, film grain, lens distortion, lift gamma gain, motion blur, shadows midtones highlights, vignette and white balance
Audio effects on audio tracks, 11 of them: chorus, compressor, distortion, echo, flange, high-pass, low-pass, normalize, parametric EQ, pitch shifter and reverb
Music sync was rewritten. The game follows the audio clock and corrects small drift with a slight pitch change instead of a jump, so the stutter every few frames is gone
Fixed: in the editor the timeline cursor made the level clock run about 15% slow
Randomness is repeatable: the same level with the same seed plays the same on any device. The level screen has a seed field with buttons to randomize and clear it
The level screen shows the authors and licences of the level and of its resources

An object's lifetime is a start and a duration. Each edge can be anchored to the edge of the parent, so the child follows it
A layer is counted relative to the parent, not as an absolute number
