Well, after spending the entire weekend doing other things, about 7 hours ago I decided that maybe I should try to create something for this Ludum Dare after all. :)
And I *almost* done it... The game is playable, not even too ugly, but lacks levels - I managed to create only four introductory levels. And of course there are some bugs too (don't step on a human!), but it can be finished without much problem.
Tomorrow I will travel the whole day, I doubt I will have the energy in the evening to complete the game, so I just submit it in this state.
The game is made with pico-8, the source code is in the cartridge ping as usual (If you know pico-8 (you should, it's great!) you know what I'm talking about).
Good, simple idea. Kept me going for a bit. Nice that you added in the "direction" so you know where the humans will go. Would've been tough without that.
Enjoyed the levels that were there, and I would love to see more levels for this.
