The core idea is very creative and creates a surprisingly challenging task. Constantly scanning the screen, noticing whose life cycle has ended, and quickly typing the first letter of their name keeps you focused and engaged.
Personally, though, the presentation made the gameplay less enjoyable for me. Watching simple circles for an extended period felt quite abstract and visually repetitive. I think the same core mechanic could become much more engaging with a stronger visual setting—for example, small characters moving around a top-down town, with visible events happening to them before you have to collect them.
The current visuals work well enough as a game jam prototype and successfully demonstrate the idea, but for me they are the weakest part of the project. The concept itself is strong, while the gameplay and presentation could be developed further to make the experience more satisfying.
In any case, well done for completing and publishing the project!
