Touhou Limitation of Imagination (东方远空界) Demo Hard 1cc - Reimu A
12New Chinese fangame demo.
The system feels like a mishmash of other systems, but is most similar to Ephemeral Unnatural Balance.
Collecting the diamond limit items charge the left meter. Once it's full, you may start a "trance" of sorts with C. Grazing under limit trance (my name) increases score multiplier on the reward. Staying under trance counts down a timer on your character; when one ends, the next one starts. Each timer you successfully sustain nets you another life piece when the trance ends. Almost exactly like EUB.
The difference is that the ceiling for life pieces increases as time goes on. The first three trances you can only get 1 life piece max (only one countdown happens), the next three you can get 2 pieces max per trance, and so on. Additionally, the difficulty doesn't increase under trance.
Thus, you can either play conservatively by ending your trances early and getting surefire life pieces, or trying to go long for many pieces at once. If you get hit during a trance, you don't die, but you get no score or life pieces.
There's a secondary system as well where grazing outside of trance charges the meter above your character. When charged, a circle will appear around you. Pressing C at this time will instead "mark" all enemies on screen. Marked enemies are made significantly weaker and drop double the number of items. It's purely to assist in charging your limit meter.
