Okay. The biggest problem for me right now is the incredibly awful interface. The lines are climbing on top of each other, which makes it almost impossible to read it. In addition, the "visible" cursor and the "real" cursor do not match. That is, when I try to put, say, a platform, it is not placed where the cursor is, but above and slightly to the side. Sometimes not a little. And the closer to the right side of the screen, the greater this difference.
And when I get excited and sit down to do something... all the excitement instantly evaporates when I remember what a pain in the ass that awaits me.
P.S.: I hope the translator didn't distort my thoughts too much...
