Thanks a lot for your feedback, I really appreciate.
I would love to continue developing this mod, but at the moment I am developing an other one with Sindhi, Magic of Aquaria, and I told her I would not spend too much time on this

Here are some things I had in mind for Angry Li :
- Being able to drop exploding mines while holding the right button.
- Being able to fire a laser ! (super attack)
- Additional secondary attacks.
- Show the submarine "health" bar on screen
- Add checkpoints where all the structure points would be restored
- More maps with the other Aquaria environments and creatures
- Rocks falling from the top that you have to avoid
- Walls that you have to destroy in order to pass
- Giant creatures. (take existing creatures and scale them bigger and change the color)
- Mia boss.
- Being able to free Naija at the end.
That would take me months to do, so this will wait ...
But if someone wants to take the mod and expand it further it would be awesome. New maps with creatures are easy to do, and for the scripting I would give a hand

For now there is an additional map you can play with, enter the editor with tab, and load the map "lisub0", this is the map I used for development. (mm... seems the weapons are not active, you have to play the main map until you get shock, and then you can use weapons)
