Trash It is an obscure puzzle platformer from 1997. It's quite unlike anything else - the gameplay consists of destroying obstacles and enemies using your hammer (and lots of level-specific items), navigating through environmental puzzles and hazards, collecting timmies (small running hammers) with a vacuum cleaner and reaching the exit within the time limit. On the world maps, you progress by clearing levels and buying stronger hammers with timmies to destroy blocking walls. The game has a very humoristic tone but the gameplay is serious and will kick your ass after a while.
I think the game has great potential for an entertaining TAS due to its mechanics and that it becomes quite complex. There are lots of places for optimization, both in strategy since you only need a certain amount of timmies (and later also percentage of level destroyed) to progress so you can usually skip big parts of levels and sometimes whole levels, and in movement since there are advanced moves such as somersaults and ground pounds which speed up things considerably.
There aren't that many videos on Youtube about the game and most have either have poor audio/video quality or poor gameplay so a high-quality TAS would not only be entertaining but also a great showcase of the game. Here is the best playlist I've found, check out a few different worlds if you want to get a feel for the game:

There are special hammer moves for certain hammers but only one is described in the manual (it is necessary for game progression) and all other ones are secret. I have never figured out any of the other ones and I haven't found any information about it online either. Considering that the only known one is extremely powerful, the other ones should also be powerful and make a huge impact on the gameplay if found.
If anyone would be interested in TASing this game, please reply here. I'm not a TASer but I'll be happy to help as much as I can :)
