Thanks for playing our game!
Yes some of the levels are easy to clear but hopefully get harder as the game progresses! You can also challenge yourself to perfect a level by collecting all the mice and not using any apples but, this isn't necessary to beat the game and rather an optional challenge to 100% the game
Thanks for the feedback on the controls! Could you elaborate on the frustration you had with the controls and the invisible buffer (I'm not familiar with this)?
You can use the arrow keys to move if WASD is unfamiliar and you can also hold down a key to go that direction. Any extra details you can give would be extremely helpful thanks!
