I love this.
Stepping forward bump that's a wall.
Thanks^^
I've just made a few quick fixes, the web build is version 2 now, but version 1 is still available.
1) Now you just bump into a wall rather than step forward (but if you liked the other way better I can easily switch it back).
2) Slightly increased volume.
3) Placed gold in a somewhat harder to reach spot. The original placement was from Russel & Norvig, but it was a bit too easy to find the gold by accident.
Uploaded version 3 with two changes:
1) Stop all currently playing audio by pressing 's'. Unfortunately this doesn't work with the web build because "The seek function for sound sources is not implemented." (LoveWebBuilder).
2) Input for left/right/forward throttled to one per second. Previously you could move multiple times and get feedback only once, which could lead to confusion.
