Main hotkeys and cheats:
     Space (Space) - the most important cheat code. Pressing this key instantly completes the current level (puzzle) with a successful result Steam Community Guide.
     F - in some versions of games from this developer allows you to automatically complete an action or level.
     Esc - exit to the menu where you can view the progress or gallery.

Tips for quick passage 100%:
     Unlock the gallery: Simply start the level and press Space. The game will count the victory, and the corresponding image will appear in the gallery.
     Achievements: Using the Space key does not block the receipt of achievements on Steam, so this is the fastest way to get "platinum" (100% achievements) in a few minutes.
     Gallery: All open content is available in the main menu. If you missed a level, you can select it again.

Please note: In similar games (for example, Sweet Coffee Shop or Sweet Dreams Cafe), the cheat mechanics are identical - the Space key works as a universal "victory" button for Steam Community Achievements.
