Ok both these games are probably not TAS-worthy (the first is too slow paced, the latter is too predetermined), but I want to mention them here anyway.
Finally I was able to find the name of yet another game I was thinking of.
There seem to be variations of a puzzle game but the objective is more or less the same. You play as a cat and interact with objects in the game. So e.g. you can push water into fire, paper into envelopes, etc. I definitely remember this game for its sheer number of objects you can interact with.
- Superkatze (super cat)
- Irre Katze (crazy cat)
- Knallkatze (bang cat)
- Schiebekatze (push cat)
- Lidoskatze (lidos cat)
E/ Game is available for download but can't tell where.
