What a great maze maker the bulk of a game in around 100 LOC, nice.

I did not care for key action and find the following fix much better:

Does it work better for you?

I request a Legend to explain the the symbols in maze. Hate to mistake a gem or magic potion for Yosemite Sam.

[James D Jarvis]

I'll be slapping in a help screen or an intro screen eventually. the diamonds are gems, the hearts are health potions , and the starbursts are power runes. the monsters are ants, spiders, and orklins. probably changing the whole input scheme so it's more properly "roguelike" whit one turn per key press. 1st test of my monster code and most run into a corner or even worse tunnel off the screen in about a second. Already killed the ant tunnelling code. If I can squeeze some time in this weekend I hope to get the monsters working.

Hi @James D Jarvis, did you try the alternate key action I posted? For me, it is much easy to step only once to turn a corner and go a different passage way. Originally in your code with _Keydown() I jump past, too far one way then too far the other, not fun.

A monster could go same direction it is already headed (80%) or reverse -dx or -dy (20%), or any avail direction if at intersect of passage way (25% maybe).
A smarter one would head towards hero's x, y at every possible opportunity.

[James D Jarvis]

Haven't had a chance yet. I might be able to get to it later tonight or tomorrow. Thanks for the input.

[James D Jarvis]

Okay so _keyhit as opposed to keydown does seem to work better in a tight maze, thanks for that.

[James D Jarvis]

gosh darn... I'm messing something up big time.  might have to strip this down and rebuild from scratch. More happens in this listing just not like I wanted it to, posting this failure as an example of what no to do:
