Angel Beats! -1st beat-

Windows 2015
Set in the afterlife high school where souls remain until they “graduate,” Angel Beats! -1st beat- casts players as Otonashi, caught up in the S.S.S. campaign against the mysterious Tenshi and the systems that enforce the school’s rules. Stages move between compact school corridors, rehearsal-like rooms, and open segments where enemy formations surge in waves. Progressing through the story places the player in scripted confrontations and free-form battles, maintaining a constant sense of pressure as the background of everyday school life gives way to sudden fights choreographed to music. Gameplay blends rhythm action with direct combat. Players take positions in each encounter and respond to timed inputs matching on-screen note patterns, translating beats into attacks, dodges, and special maneuvers. Successful timing builds momentum, allowing stronger strikes and interrupting enemy actions, while missed beats reduce effectiveness and can open windows for counterattacks. Combat is structured around short bursts rather than slow attrition, with enemies appearing in predictable patterns that reward reading the beat sequence and repositioning at the right moments to keep combos alive. The game’s mechanics emphasize readable lanes and responsive animations. As songs advance, note density and attack variety increase, requiring continuous coordination: strike to stun, evade to avoid incoming hits, and trigger character techniques at rhythm-supported moments. Certain enemy behaviors are countered only when the player commits to the correct pattern, turning each track into both a performance and a tactical script. Between battles, the story unfolds through character dialogue and brief scene transitions that connect the rhythm challenges to the ongoing conflict within the school. Visually, Angel Beats! -1st beat- presents characters in vivid, anime-inspired stylization, with clean outlines and expressive facial expressions carried into in-battle motion. Backgrounds remain recognizable as school locations—desks, hallways, and familiar fixtures—framed by dynamic effects when rhythm-based attacks land. Enemy designs range from humanoid silhouettes to more unusual forms, each reacting with clear hit feedback, flashes, and motion cues synchronized to the music. Audio drives the entire experience. Each stage is tied to vocal tracks and instrumental arrangements associated with the Angel Beats! universe, and the timing windows align with rhythmic cues rather than generic metronome behavior. Voice lines and character callouts punctuate key moments, while sound effects for slashes, impacts, and special techniques reinforce successful timing. The result is a performance-forward battle system where mastering the beat translates directly into control of the fight, turning every confrontation into a synchronized showdown.

Planetarian: Chiisana Hoshi no Yume

Windows 2004
In the future, mankind has almost annihilated itself due to a long global nuclear war caused by panic over the depletion of all Earth's natural resources, and the subsequent failure to colonize other planets. With 'The War' over and only a few thousand people left, a constantly falling rain that is potentially deadly due to years and years of nuclear fallout threatens to destroy the rest. The protagonist of the story is a scavenger who has sneaked into an abandoned city. He takes shelter from the rain inside a department store building and finds something very unexpected on the top floor. . . . Planetarian is a 'kinetic novel', i. e. a linear, non-interactive visual novel, powered by Key's RealLive engine and takes about 4-5 hours to read. Once finished, options appear in the main menu that allow you to revisit the CG and listen to the music.
