Wait. I think I played your game too!!! It was fun. Sorry level 4 was tough. I was trying to balance it but I ran out of time for making sure that level was playable for all people (such is the way for games on a deadline). I mentioned it in the other comment, but I was working on a slightly shorter timeframe, so I didnt get to add some of the quality of life elements to the controls like a movement buffer to make the movement more fluid (I also should have definitely added long press for continuous movement). Definitely something to remember for next time I add grid based movement to a game.
Thanks for playing and for the comment! :)
