When I first saw Lost in the Wild's game world I didn't expect too much, but after a few minutes of play I was pleasantly surprised. The "core" game loop is quite a fun little one. Gather speed, use that to gain power and then find rocks and take out the tribe. Obviously the sound effects are spot on too.
Not sure how the "engaging" with a tribe worked - as it seems you have to kill them to progress. Here's my feedback on what I would work on next if I was making this game.
+ Ensure no tribes people near player at start of game to avoid instant attack\death.
+ Add HUD item showing how many tribes people remain.
+ Maybe add health rather than instant death - also add health to HUD.
+ Add controller support, should suit it well.
Keep up the good work.
