It is a good game but I think the signs have too much clutter for conversing. Some things I think should be added as well.
- control mapping
- having the basic movement keys as pictures on the level when you fall (seems that it should be obvious, but I have found it is a good idea to implement these things)
- have the tutorial be something more like the signs were left behind by someone who fell down before you and left them for you (I been down here for a while, i should probably move on, i figured out you can press "space" to jump) (apparently, by holding space in air we can use our ears to float is useful down here)
So far the game is pretty good an well made. Some name ideas you may like or to inspire
- Floppy's Trip (ears and they fall down the cave :P)
- Deep Descent
- Dangerous Dwelling
- Cave Game (jk)
