Here's some tip for your game:
- Flying/Moon jumping (shift jump) feels useless when you can infinitivly jump in the air... (i read later that is a bug, sorry)
- Make the collectables easier to find... And add some more stuff to do...
- Make the eneny radar more intuitive, or explain it in the help session
- Don't let the player go under the terrain, or even better, add invisible walls at the edge of the map
- Reduce the amount of fog
- The horn. what it was for, besides making me jump out of my chair and make me worry unnecessarily for the bug lord???
