Change the spiral into a Frog Puzzle in the 1st assignment?

The idea is to adapt the Grid World (e.g. 1xN grid) to facilitate Frog Puzzle solving. If not possible maybe we should invest time in developing standalone environment (text based output with unicode characters should suffice 🐸🐸🐸 ).
It might be beneficial to change the 1st assignment -- the spiral -- into formative feedback, and task students with writing simple Frog Puzzle solver instead.

@flach I had a look at this and unfortunately it's not straight forward.

It's probably a better idea to write (student project) 🐸Frog Puzzle🐸 environment from scratch.
