Named for a velvet worm. This is rather like Snakebird, but with mining. I like the idea. It’s hard to properly understand why one gets buried, though; this is a problem which would, I think, be solveable with better graphics. I think the rule is this: if you’ve dug a hole so that a contiguous block of mud above you is completely separated from a block below you, then that block falls and crushes you. But it’s hard to tell because there’s no animation; digging the final piece of that hole immediately transitions to you being dead. If I could see the block above me fall, then it would be much clearer what was going on, which I think would help a lot. This prototype does suggest that there’s an interesting game here, though, and I’d like to see more of it once it’s completed with animation, maybe some improved graphics, and sound!
I named it after a worm because it was a snake-like with digging :) Just like snakebird is snake-like game where birds are involved...
As you and more people noted, the game misses the animations of 1 pixel resolution (the game has only 4x4 blocks) to show when the soil collapse and when the worm falls, but I really had not time to implement them with a small son to take care of :-p
More things I would like to add are sound (of course), falling bonuses to create more complex puzzles and a better font.
The current rules are: first the worm move, then the soil collapse, then the worm falls (all in an instant)
And the soil collapsing rule is that soil that is connected to rocks (the white ones) by a 4 connectivity won't fall.
Thanks for the review! :)
