It's an interesting concept, but too slow going, so the movement speed can definitely be increased. I'm also not a fan of the color scheme chosen; the green background with black tiles is quite jarring. I think this idea may work better in a level format, possibly with a limited number of "Bequeaths" per level or a time limit, or maybe just the addition of enemies could improve an endless version of this game enough to be fun. Overall, it's not too good, and I'm not excited about playing more, but I do think a better game could definitely be made with the same premise. Sadly the author no longer appears to be active, so a bigger and better version of this may never be made.
