Hey ! Thanks for this amazing feedback.
Especially that the game design is good. This because I am currently (beside my fulltime job) learning to become a gamedesigner. Through game jams I test my learned knowledge and I also learn programming.
You really think i'll have to expand the game? making puzzles is quite difficult, you have to think about it a lot haha!
Where would you want to see the instruction then? Because there should always be a way for the player to know how to play the game. Maybe i should keep the instructions more compact. like "hey a stone, you should check out what it does" vibe.
Again, thanks for this amazing feedback!
