Thanks !
The help menu was actually a last minute addition, so I initially purposefully planned to have tutorial level. (also, being tutorial, they were really easy to design :) )
About the movement, well... yeah, 500ms to complete the movement was too much. I could have changed that. although, the initial idea was to have more modifiers tile including one making the movement double (moving 2 tiles at once) Doubleing the movement speed. I did not have enough time though... maybe in a future version ?
as for the movement direction, Yeah, something indicating in which direction the characters would move would have been helpfull (even for me) but with the time constraint, choses had to be made.
But hey, thanks for taking the time to evaluate the game and make the comment, makes this first GameJam an even better experience !
