Now THAT'S a clever take on the limitation.
As someone who struggled with my first use of a sequencer this jam, the attention you put into the first minute of experience in this game turned out just lovely. All of the screens are informative, absolutely beautiful, smoothly transitioned and very well timed.
You've managed to do a lot with a little for gameplay, and the mechanic was motivating enough for me to play a few times. Were the big stars supposed to be pickups? They weren't interactable for me, so it made the dominant strategy just walking as little as possible back and forth whenever a spike came out. I was thinking it could be more fun if patterns of spikes came out (i.e. only one safe tile vs only one dangerous tile) or if there was a reward on screen motivating additional movement (maybe that's what the stars were though).
All and all, an almost perfect, extremely well polished and loved game in my book. I genuinely can't wait to see more of what you come up with.
