Patch Notes, v0.4.37

Sparrow Warfare · published 24 Apr 2026, 12:34 UTC

All newsPlayers around this dateRead on Steam

This is easily the biggest update to the demo since we launched. It adds a whole new subsystem for building your little tile-powered engine: discarding for profit. We were looking for ways to encourage discarding tiles for a while and now we've finally found a good one: adding status tiles that sit in your hand until you find a way to remove them. And while they're sitting there (or when finally discarded) they have an active effect. For example they might heal you at the end of the turn.

In order to make the game more approachable we're also kicking off things by showing you the intro and then dropping you into the tutorial now. This only happens for new players.

Finally we've updated the look of the tiles to look more physical (to have more depth) and we've fixed a ton of small bugs.

New wildtiles:

  • Lullaby: Playing a Song hand weakens a random enemy.

  • Peel: Remove all opponent shields.

  • Recaw: Resurrect a random Phoenix tile.

  • Sleet: Shoo all frozen birds.

  • Breathe: Discard your hand. Get 1 strength per discarded tile.

  • Shed a Feather: Pick any hand tile to discard.

  • Chaosball (Fire): Randomise opposing tile order.

  • Demote (Fire): Push the first opposing tile to the back.

New persistent status tiles:

  • Echo: Draw 3 tiles when this tile is discarded.

  • Golden Echo: Draw 3 wildtiles when this tile is discarded.

  • Alarm: Awaken the boss when this tile is discarded.

  • Hot Potato: Receive 3 *burning* at end of turn.

  • Whistle: Draw an opponent when this tile is discarded.

  • Gremlin: Discard 3 tiles at end of turn.

  • Gesundhog: Heal 1 per tile in hand at end of turn.

  • Cone of Shame: Heal 3 at end of turn.

  • Die Münze: Fill hand when this tile is discarded.

Changes to existing tiles:

  • Olympic creates a Hot Potato now

  • Arson creates a Hot Potato now

  • Fan Club is now aromatic

  • Ear Worm creates an Alarm tile

  • Discarding tiles (e.g. Falling Upwards) made less rare in early levels

Other Gameplay Changes:

  • Increased probabilities of tiles that discard tiles

  • Added tiles that generate positive status tiles or enemies

  • Pump-A-Run modifier description updated to reflect addition of Snipe wildtile

  • Added vapour info to Steam Bath, Water Down, Water Landing, and Celsius

  • Attack sum now also visible while tiles are being played (hidden during enemy phase)

  • Hightail & Shoo tiles now animate the shooing of birds

  • Boss idle animation added

  • Tutorial now shown at the start for new players, with a tutorial button visible when the tutorial modifier is active

  • Flight 1 is now the entry point for all new players; the story intro has been removed from Flight 2

  • Music tracks replaced and new ones added, with correct credits

Bug Fixes & New Features:

  • Fixed transparency issue in the health box (new corner overlays)

  • Fixed tiles appearing too small in the loading blocker despite a low tile count

  • Fixed music stopping when exiting the stats menu

  • Fixed demo incorrectly labelling the start screen as "Flight 2" when it leads into Flight 1

  • Fixed Invincible Buff being removed after the first hit instead of persisting

  • Fixed shooing birds sometimes crashing the game

  • Fixed The Cuteness not updating the enemy attack preview value

  • Stats menu now has a title

  • Run name now displayed on the loading blocker

  • Loading blocker converted to its own scene, active while the game is loading/preparing

  • Bird cone lowered slightly to fit under the new top-left icons

  • Status tile backgrounds cleaned up

  • Many tile icons reworked

  • Game now starts in Steam language unless the user has manually overridden it (override is now saved as a config)

  • Various localisation fixes

Known issues

  • There are still issues when connectivity is bad (i.e. crash during run upload, Steam trouble)

  • I’ve half-added controllers support in the beta branch. Hope it doesn’t break anything.
