Huh, this concept reminded me of my game a lot... :D
The game is really well made, although the narrator was kind of repetetive after the first few deaths. The theme was implemented wonderfully, although I don't really see any educational aspect. I guess problem solving, coding, something in that direction?
I think the respawn time could've been made shorter. After you die, you immeadeately want to start playing again now that you know that that direction is blocked or not. But the long wait before the respawn animation and the respawn animation itself is a bit too long in my opinion. Clear markers for one unit of moving would also be a great addition, so that you never accidentally are one moving card too short to reach the end.
Anyways, it's interesting to see that someone had a similar idea, and the game is well made. Good job!
