In Immaterial and Missing Power Performance Test 1, the bar at the bottom of the screen was a bomb gauge, which would fill up as you hit your opponent or were hit by them. In order to unleash a bomb, the bar would have to be at least fully blue and blinking. By getting hit past this limit, the gauge would briefly start filling up with red colour, but the red portion would drain rapidly.
When you triggered a bomb, if your gauge did not have any red portion, it would drain completely. But if you had even a tiny speck of red, it would drain only up until the previously red portion, which would become blue afterwards.
Another thing in this version is that the bomb did not make any sound when triggered. The sound effect was added in Performance Test 2.
In Performance Test 2 and the trial sold at Comiket 66, the bomb gauge can be found under the spirit bar. It had a similar behaviour as in Performance Test 1, however you could get the gauge fill up with red way more than you were able to do in the previous version.
In the web trial, the bomb gauge was removed completely and was replaced by two stars indicating how many bombs you have left. Once you consume at least one bomb you can get another one by fighting. When triggering a bomb, the spirit bar would refill entriely and your opponent would be damaged. This behaviour changed in later full versions, which have been detailed at: /post/820873738496180224/.
