Thanks for the feedback.
Yes, the game has a rather classical difficulty level as known from older games. I have already noticed that not everyone likes that.
The lives are saved, but only down rounded 50% of the maximum lives are replenished (if I remember correctly). For example 2 of 5 , 3 of 6 .
I am currently working on Bobo The Cat 2 and there are 3 difficulty levels there. On the standard difficulty all lives will be replenished at checkpoints. Also, when you die you are only reset to the checkpoint, but you don't lose any upgrades or solved puzzles.
What I want to say: For Bobo The Cat 1 I didn't want to compromise, because I wanted my first game to be 100% like I imagined it, but for the sequel I listen to the critics of the players.
Backtracking is possible in Bobo The Cat by the way but not immediately. I wouldn't recommend it before you learned the fast travel function anyway.
