Short description

Once Upon a Slime will be the game that starts my career as a solo game developer. This game is an adventure / bossbeater game about a little slime trying to escape a dungeon full of bosses. Beat them all to solve the mysteries of these dark dungeons!

About this game

Once Upon a Slime is the first game that I am making in my career of a game developer and is an arenashooter / Bossbeater game about a little slime. At the moment there are 3 gamemodes in development: - Endless / Survival Mode - Story Mode - Pacifist Mode Endless / Survival Mode will throw you in an arena with an infinite spawning number of enemies. Shoot enough of these enemies and you will level up, making you able to pick new weapons, abilities or upgrades. There is also a store in this gamemode in which you can buy certain skill upgrades or new special weapons. Story Mode will take you on an adventure in which you need to progress through levels and beat a couple bosses along the way! Pacifist Mode also throws you in an arena with spawning waves of enemies except you are not able to shoot any enemies! make sure to dodge al those scary slimes by using the dash ability! Controls - AWSD or arrow keys to move your hero! - Left click to shoot - Right click to dash

Price History Overview

USD uses SteamPulse's own locally recorded daily store snapshots, so this overview reflects the exact regional price history that SteamPulse has captured for this currency.

Coverage And Tracking Window

  • Snapshots: 1
  • Coverage: Sep 22, 2026 to Sep 22, 2026
  • Lowest observed: $0.00
  • Highest observed: $0.00

Once Upon a Slime's USD price history spans from Sep 22, 2026 to Sep 22, 2026, with 1 recorded snapshot across 1 calendar day. Each row records the available final price, listed base price, and discount metadata for that observation. Within this coverage the lowest recorded price is $0.00, the highest is $0.00, and the first visible tracked price is $0.00. These comparisons apply only to the snapshots SteamPulse holds; missing observations can contain changes that are not represented here.

For USD, SteamPulse uses locally captured regional storefront snapshots and does not reconstruct older prices with exchange-rate conversion. The chart and table show the values recorded for this exact currency from the stated coverage start. Additional snapshots extend that record, but they do not fill unobserved days or prove what the storefront displayed between observations.

Discount Windows And Sale Timing

  • Discount windows: 0
  • Discounted days: 0 days
  • Deepest markdown: No discount tracked
  • Latest sale window: No sale window tracked

Once Upon a Slime's tracked USD rows do not contain a discount window. This means no available snapshot in the stated coverage has usable discount metadata; it does not prove that the game was never discounted. Missing snapshots or archived rows without complete metadata can hide a sale, so SteamPulse does not infer pricing strategy from this absence.

If a later snapshot includes discount metadata, it will appear here with its recorded depth, price, date, and sale name when available. Until then, this section should be read only as a description of the available rows, not as evidence about the publisher's promotion policy.

Observed Price Changes And Stable Runs

  • Observed price drops: 0
  • Observed price rises: 0
  • Longest stable run: 1 day of uninterrupted daily tracking
  • Current run: 1 day of uninterrupted daily tracking

Outside rows carrying discount metadata, the tracked price has not recorded a separate price rise or drop yet. That means the observed undiscounted level has stayed stable across the snapshots SteamPulse currently holds. This is a statement about the recorded coverage only; it does not prove that an older or missing price change never happened.

The longest unchanged price stretch in the current record lasts 1 day of uninterrupted daily tracking at $0.00, from Sep 22, 2026 through Sep 22, 2026. Among rows without discount metadata, the longest unchanged run lasts 1 day of uninterrupted daily tracking at $0.00. The latest run records $0.00 for 1 day of uninterrupted daily tracking as the same recorded undiscounted price. Run lengths describe consecutive stored observations only and do not establish that a price is permanent.

Latest Snapshot And Sales Context

  • Current price: $0.00
  • Current list price: $0.00
  • Distinct observed prices: 1
  • Source mode: SteamPulse local tracking

The latest tracked snapshot records Once Upon a Slime at $0.00 in USD, with no active discount metadata. Across the available history SteamPulse has recorded 1 distinct final price in this currency. This supports comparisons with the lowest, highest, and most common values present in the retained record, subject to the stated coverage limits.

The live sales view and Steam sales record provide calendar context for these dates. A date overlap can be compared with a named Steam event, but it does not prove why a publisher changed a price. As new daily rows arrive, this overview recalculates its observed prices, discount windows, and run lengths automatically.
