1. very unlikely, but the free save function can reduce the difficulty of a stage a bit if it's too much
2. probably not leveling, but i think it'll be interesting to have some temporary buffs or something similar
3. the game is going to stay free
4. more info about them is coming for sure!
5. i do have something like that planned!
6. maybe not physical mutations, but some teleenas are going to have special skills. I have 17 different teleenas planned so far.
7. yes, i plan to have them playable in some scenarios in the future
8. very likely to add more hints before stages
9. i left it there for it to be like an extra thing since it's default for the engine, but not really the intended way to play
10. for now, it can't be changed, i'm sorry for that
11. probably not, but it'll contain some alternative playable scenarios
