I love Pocket Frogs and Tiny Tower so I am really looking forward to this game.
I like pixelated graphics because the games I grew up with looked like this. But I can understand that younger/newer players don't like graphics like this very much. They are not used to see something like this.
But everyone who seriously tried out Dream Heist ( yes I did so so I could write a long review in my country's App Store) has to notice that its graphics are really really bad. Yes, it looks less blocky than TT, but that is the only positive thing you can say about its graphics. The people in the game look really strange and wobbly like bubblegum which was chewed to death. Every room has the same boring striped wall and checkered floor just in different colours. While I tried out the game I built around five residential floors and every one of them "featured" the same plant. Some of the other furniture is also just copied and pasted in different rooms. In TT every room looks really interesting and has small but beautiful details. The beach apt. for example has a floor which looks like sand on a beach. My Tiny Tower is about 90 floors high and I am still looking forward to each new room, because there is so much creativity in the graphics. In DH i was bored to death after about ten floors, because they all look the same.
