I skipped a few levels in the middle with the tab button, to be honest, so if you want people to really go through the game, try to deactivate that possibility.
The Level with 33 gave me a hard time. I thought it's a really hard puzzle, since there were 32 carrots on the screen and the numbers showed up as 32. Btw, if you click on a few of the bottom row carrots there, you get thrown two levels back - try to fix that please, it's quite annoying!
Overall it was fun. The difficulty is really jumping around a lot, but because of the hard levels, it makes fun (at least for me). It seems like a game that's good to play with parents and kids, since the parents can have a hard time at the more advanced levels, while the kid can have a bit of success solving the other ones.
For only ten levels I don't see why it's necessary to make up a level select screen. It's fine like it is.
This is also a good mouse-control trainer. It requires a fluent handling of your cursor.
Of course this is not an overall good entry, but it's not meant to be. For what it's meant to be, it's perfect, and I had a fun little time with it. Thank you!
