i really like the visuals, but the sound is just meh. the footsteps are louder than the portal sound, which in my opinion should be louder bc you hear it more rarely and its more important, and when you move diagonally, two footstep sfx play at once. the concept could be more creative, but i cant really blame you bc my creativity is 0 lmao-
the gameplay kinda reminds me of the pokemon ice sliding puzzles, dunno if that was maybe an inspiration.
i cant really see how this fits into the "limited space" theme tho? idk maybe im just dum (im am)
overall, maybe an average of like 3 stars- keep coding tho, ur doing great!
