Climb! Postmortem

Climb! on Itch.io

Introduction: Climb! is my submission to the Itch.io Falling Block Jam 2025, a tribute to the block genre with a twist. Players begin deep underground, trapped in the earth's core, and must ascend by leaping across formations falling from above. Each level is a race against time, faster completions earning higher scores, while hesitation risks being burned. As players progress, the challenge intensifies, demanding carefully planned jumps to survive and reach the surface.

What Went Right

Great UI Communication: From start to finish, Climb! maintained clear and intuitive UI design that supported gameplay without distraction. The title screen offered a clean layout with a compact, unobtrusive control guide, making onboarding seamless. During gameplay, the HUD was minimal yet effective, tracking progress clearly while keeping the player’s focus on movement and timing. Game over states were communicated instantly, with straightforward buttons guiding the player’s next steps. Successful level completions triggered a brief celebratory UI moment, reinforcing progress before smoothly transitioning to the next challenge.

Player Feedback: Climb! delivers responsive and engaging feedback through sound, visuals, and UI cues. A playful background tune sets the tone, while victory is celebrated with energetic audio and visual flair. Defeat is punctuated by a sharp burning sound, reinforcing the stakes. Each jump triggers a satisfying sound effect, giving players tactile confirmation of their actions. A depth meter on the left side of the screen tracks progress upward, rising numbers signal success, while falling values warn players they’re nearing the burn zone. Together, these elements create a tight feedback loop that keeps players informed, motivated, and immersed.

Sense of Urgency: Players begin on a seemingly solid slab just above the burn zone, but that illusion shatters with their first jump. The platform collapses instantly, leaving them no safe base and forcing reliance on falling formations to survive. From that moment on, every leap is a gamble, every hesitation a risk. The mechanic created a strong sense of urgency and surprise during playtesting, evoking exactly the emotional tension I aimed for: panic, momentum, and the thrill of narrowly escaping the earth’s core.

Spirit of the Jam: The Falling Block Jam 2025 challenged developers to celebrate the combination of blocks and gravity in video games, with classics like Tetris and Dr. Mario as inspiration. Climb! embraces this spirit through randomly spawning formations of varied shapes, echoing the unpredictability of falling blocks. As players complete levels, each one increases the fall speed, mirroring the escalating pace of Tetris. At higher levels, formations begin to rotate as they fall, introducing a fresh layer of challenge and paying homage to the rotational mechanics of the genre. This twist not only honors the jam's theme but reimagines it through a vertical escape narrative.

What Could Be Improved

Shape Creation and Asset Integration: Early in development, I realized Unity’s default primitives didn’t include the shapes I needed, specifically diamonds and triangles. Rather than download a full asset pack for basic geometry, I opted to create them myself in Blender. While the results were simple, this choice kept the project lightweight and under control. I also encountered challenges integrating textures from an asset pack, as they required multiple adjustments to align with my game’s visual style and mesh UVs. These moments highlighted the importance of having a small library of reusable shapes and textures ready for future jams, and reminded me that even basic asset work benefits from intentional design.

What I'd Explore Next

Introducing falling powerups like double jump or wall jump to encourage risk vs reward decision-making as the player climbs, adding a layer of tactical urgency

Adding dynamic enemies, such as tunnel worms, burrowing creatures and aerial threats to add reactive challenges, rather than just environmental ones, encouraging adaptive play

Creating additional level types such as new biomes, additional goals with relevant mechanics, and varying difficulty levels to choose from

Conclusion: Climb! was both a fun and challenging project, made even more rewarding by the constraints of the Falling Block Jam 2025. Working within the jam’s theme and time limit pushed me to think creatively and iterate quickly. As my first 2D game, it introduced a host of new tools, workflows, and design considerations. Each obstacle became an opportunity to expand my skillset. The experience not only sharpened my technical abilities but deepened my appreciation for responsive design, player feedback, and modular systems in a 2D context.
