Polly-B-Gone is a platform game in which you are a cute robot who needs to escape from a laboratory. The place is full of platforms and precipices, so you really need to be careful when you command it. If you fall off the platforms, you will have to start again from the last checkpoint. You have unlimited lives, so don't worry if you die a lot of times. There's also no scoring system, as the objective is to advance as far as you can.
Unfortunately, you cannot save your progress, so once you close the game, you will have to start everything from scratch. Moreover, there is no main menu or any options whatsoever. There is also no way to know how many levels there are, and from what I've seen there is only one mode. I would really have preferred if the controls were the arrow keys and not some keyboard letters, which for me are more uncomfortable. It took me some time to get used to them and not fall all the time. The game is simple, but enjoyable, and it is also very challenging. From time to time, there are dialogues that help you understand the story behind the game and know what to do. Graphics are simple but attractive, sounds are nice, and the music is suitable, but it gets annoying after some time.
In short, I suggest you try Polly-B-Gone and see if it works for you.
