Hmm, I finished it, but it didn't really feel like a challenge. For one I think it would have been better to not grey out certain options and let people make the mistake of falling to their death. I do like the idea, but I feel like something was missing.

Fun game with an interesting idea of rolling to get the number of action points available. Apart from the undo button that so many people already mentioned, I would also add a "restart" button (because there is a bug in level three where I could not get back from the rightmost column and could not finish the level) and I would change the turn icon arrows to these ↺ ↻ for less confusion. 

Took me a round to get used to it, but I like it, it's an interesting idea :)

Though also too easy once I figured out

Nice game!  Took me a second to get the controls right but I figured it out!

Cool concept! Quite hard starting from level 3 if you don't get good rolls, i need to git gud...

I agree with the comment from scschulz2, an undo button during the planning phase would be a must, i clicked on the wrong button by accident twice and i knew before starting the execution phase that i was going to die :'(

Congrats on doing a cool game without using real game engine, it works very well and it's quite enjoyable to play! 

For a one man team, it's a reall feat of strength.
