Wow
This, and “There is nothing here” are two masterpieces of a game.
You need to be more well known, Adrien. You have talent here. Keep sharing with the world.
There Could Be A Thing Here when tho?
I've also had an idea on how the game would work.
It merges the two previous games (tinh and twsh)
You must use twsh to progressively create powerups
then you swap to tinh and collect them to progress through battles
The reason, lore wise, is that there's another entity coming to kill the both of them for something (maybe like treason, idk) So they have to work together for the first time. Maybe even, during the end cutscene, they call each other friends.
