Taisei Project Elly's Last Spell Theme: Immutable Truth

Taisei Project (泰西プロジェクト) is an open-source Touhou Project fangame. Its development was started in 2011 by Laochailan, under the tentative title "OpenTH". Akaricchi, another programmer, became involved with the project starting in 2012, and the game saw its full first release later that year.

After a five-year hiatus, development on Taisei resumed in 2017, during which the project received many more contributors. Since then, the story was rewritten and a full soundtrack was composed, and various other improvements have taken place.

The current build features two playable characters and six stages. A future release will include a third playable character and an Extra stage.

Elly's last spell.

The most ambitious and impossibly necessary tasks must encapsulate absolutely everything. Many think of science as a body of knowledge, a sealed bubble, within which all "great discoveries" have already been achieved, but the contrary could not be more true. Science is an unending series of dark curtains to pull back, each new finding more magnificent and imperceptible than the last.
