(I am now in a rush to test as many games as possible to help, so please do not mind the cursory reviewing style.)
concept equivalent to merely losing and restarting?
Controls are QWERTY-only instead of layout-independent (I have an AZERTY keyboard). I notice the left-right arrow keys make the character TURN rather than sidestep, which is also interesting (is it expected?? I suspect you can make a U-turn!)
cannot climb the stairs!!! Stuck there… ._. Or is it the end??
nice fire effect!
Some trident passageways somewhat narrow and tricky
Takeaway: classic but effective concept, and nice scenery. Just not convinced the constraint really stands out, as restarting is a classic video game idea! Liked the action.
