A horizontal platformer, recycled from what already exists
Floor Is Lava gained a horizontal platformer mode today; deliberately built by reusing the existing Climber-mode platforms rather than inventing a new obstacle type, sideways instead of up. Progress was interrupted by a canvas-drawing bug: platforms at the edge of the screen weren’t rendering into the off-canvas black space correctly, so you’d jump into it blind, only able to see bats and other hazards, not what you were landing on. Fixed by feeding the console log straight into Claude.
A one-hour session burned through the week’s Claude credits fast, split across both Floor Is Lava and Retro Racer: “quite pleased with the outcome so far” despite the short runway.
Cavern mode takes shape
By early evening the horizontal platformer was “working well”; narrow platforms, a vine to swing on, bats. By 1:05 a.m. the cavern variant of horizontal mode was 95% complete, with one lingering obstacle: an invisible wall blocking the exit from the cavern hole. Fixed a few bugs and could finally get through the level cleanly before the night was out.
