CEleste

The calculator game and C++ port by John “commandblockguy” Cesarz. Lord Funion did not make this game; the editor tooling on this page works with it and its custom-level extensions.

CEleste Studio

Lord Funion’s browser editor for levels and packs: complete logical pieces, room ordering, rotation, validation, import/export, browser autosave, community levels, and original-cartridge preview.

CELEDIT

The calculator-native part of the custom-level editor tooling. It makes CELV levels directly on the calculator with terrain and entity palettes, room management, rotation, properties, undo/redo, drafts, and AppVar export.

2ND: LEVELS

ALPHA: REPLAY

MODE: TITLE

No more instant title-screen dump.

After the final room, CEleste keeps the completed room behind a summit-style result card and freezes the run timer. You can jump straight back to the custom-level browser, replay the run, or return to the normal title screen.

For packs, time and deaths carry across the pack and the final result is shown as a pack completion.

MAKE → EXPORT → PLAY

Custom levels without format juggling.

01

Build

Use CEleste Studio on a computer or CELEDIT directly on your calculator. Both target the same CELV custom-level format.

02

Export

Export a single level or pack as an .8xv AppVar, then transfer it to the calculator alongside CEleste.

03

Browse

On CEleste's title screen, press MODE to open Custom Levels. Pick a level or pack and press 2ND or ALPHA.

04

Finish

Rooms complete through the top edge. The last room now leads to the results screen instead of immediately throwing you back home.

STUDIO QOL

Faster room editing

Studio has direct Previous/Next Room controls and [/] shortcuts, plus Ctrl/Cmd+S for project saves. The old unlisted Share Project button is gone; public level discovery stays in the Community Level Browser.

CELEDIT QOL

Less menu hopping

CELEDIT now marks unsaved edits, lets MODE quick-save a draft, confirms room deletion, and exports without triggering unsafe archive garbage collection while the graphics editor is open.
