Thank you for the game!
I liked the bird's design and animation, and the word PISA in the list title looked interesting too. With that said, more contrast between sprites and background could have made sprites stand out more. Also, the tower and the background would have benefited from more details. The tower especially looks too abstract and simplistic to me. But overall, I think that the minimalist visual style looks fine.
The idea to link in-game time to character movement is interesting! But I feel like it could have been used to create more interesting situations. For example, what if after talking to the bird you could go back in time and talk to the cat again, but this time saying that you will not build the tower?
The story is short and funny and I liked how abruptly it ends - this adds to the overall absurdist humor of the situation. But it feels like some key information is presented poorly. For example, it is unclear what the word PISA, in the end, has to do with the plot about the architect who tried to build the tower. Is it a hint that the game takes place in Pisa and we were building the leaning tower of Piza? Was the tower leaning by initial design, or was it leaned because the bird hit it? I was unsure if any of this is the case at the end of the game.
I think I've encountered several technical issues. I've managed to walk above some of the transition points and have gotten to the end room without triggering the bird to move down.
Overall this game made me smile but also left me confused about what it was trying to say. I think that this can be improved by fixing the bugs, adding more narrations in some key moments (to explain what's happening), or adding more visual details to tell the story.
