This has a Chip's Challenge vibe to it which is a plus, and also isometric graphics which is another plus. But I only see single color keys and very few obstacles... how about rabid dogs that you actually need to lock away (with a choice of moving those areas before or after), birds going after the seeds and badgers creating holes, etc, etc?
All great points! I did enjoy Chip's Challenge as a kid and the game definitely does borrow influences from the original 80s game; however, what I loved about Chip's Challenge was the problem solving. Running away from enemies wasn't what I remembered about CC. That's why I decided to make Lawnmower Challenge purely about puzzle solving. You can take your time trying to figure out the most efficient path to finish the level.
There is only 1 color key but when you consider all the possible paths with the other obstacles, a level can get extremely complex if you're going for perfection. Some of the harder levels take up to 500+ moves to complete - and that's if you're going for perfection. They can take 800 steps if you're just trying to finish them.
Here are a couple old screenshots from the original Lawnmower Challenge with the old HUD:
