Thank you for posting the feedback for the game! Yeah, I totally agree that the learning curve is still steep, and some of the tutorial levels don't feel as intuitive as they should (I guess hiding the key to restart the level on the floor of this level, where the light flickers, was a bad idea after all). I actually have more than 20 unused levels, most of which are alternative versions of introducing new mechanics. I will definitely try to come up with better ideas for them in the future since the Game Jam is over, and I have more time to update the game.
Regarding the "run game" button, there is an option in the "Edit Game" menu called "game noun" or something like that. By default, it is set to "game," but you can change it however you want.
By the way, what exactly made the controls feel cumbersome for you? The late responses, movement speed, or just overall? Thank you again, I appreciate your support; I will check out your game once I have free time :)
