Thanks for the review of our game.
Indeed, there were some bugs that were not yet fixed when we submitted the game. And as you pointed out, we may have overlooked the importance of UI hints during production, thanks for the heads up.
When I started designing the game, I did think about how to make the shadows stand out more to enhance the theme, while also trying not to confuse the player as much as possible as to where exactly they are.
Probably due to our technical limitations, designing the levels for this game on paper looks like it would be easy, but the difficulty of getting the levels in the engine to run as smoothly as they do on paper did exceed my expectations. :(
After this poll is over, we'll do possible ongoing development and make the player's path look uninterrupted by walls and such.
All in all, thanks for enjoying our game! :)
