Controls are unnecessarily confusing. I spent a few minutes trying to start the game with standard Enter or Space. Turns out "Enter" enters pause.
Then it took some minutes to be able to program robots. I understood how it works, but it would be so much more convenient if you could just press WASD and it would record corresponding direction (instead of Up/Down selecting direction from the list).
I wasn't able to pass Level 3. I though main character is supposed to go on the left spot and bomby - two cells to the right. Then, assuming bomby explodes with radius=1, main character is safe. But no - main character explodes.
So I assumed that bomby explodes far enough to explode 2 tiles away, but probably not far enough to explode sqrt(5) tiles (knights move) away, so I placed bomby in the bottom left and main character - in the top right. Main character indeed stayed intact, but bomby only exploded one tile away this time, not two.
