@fireslash I think the first level is clear enough for the new player! Maybe I am playing on an updated version? I didn't read the rule before I played. In the first, I try to escape from that enemy, I lost, I read the rules, I immediately get the point. BTW I agree with you that it should have "Moving here" hint, to develop this game deep, more enemy type is required, if the player's movement is separate into two parts, first, player press an arrow key to "try" to move, then "Moving here" tag will show near each enemy and player can press sth like Enter to confirm the move, that will be great. (or not, maybe it will make the game too easy haha)
Back to my comment, I love how you catch the theme, that's a great idea! The choice of stop and the easy ai let me feel more strategic and the game is in my control! That's awesome!
However, I think the movement of the enemy is too slow, after I get to the hidden level(I guess?). I guess that is a reward level but it becomes some kind of punishment because of the long waiting time for the enemy movement!
One more little thing, when I go fullscreen in your itch game, part the bottom screen in game don't show, I found that after I killed by an enemy below me in level 6. I think you should mention that somewhere don't play in fullscreen. (I use 16:9 monitor)
