OMFG FINALLY!
This is exactly the kind of feeling I wanted the player to experience, if you mess up.. I wont punish you, you still have a chance to fix it. Like however bad of a position u are in, you can still try fix it
This was kinda inspired from celeste, if you've played it or been in the community a bit, there's a popular meme about how the player can fall from the easiest jump and then instead of dying, trying their best to fix that situation and the game wont punish you unless you die (Not the same concept but thats where I got the inspiration from)

(From a friend who tested the game for me lmao)
In my to do list, I had a task for adding death when the train is upside down, I also planned to fail the level if the train collided with a wall
But I found it much more fun to just flick the train trying to get it back right side up xD
I initially wanted to restrict alot of stuff like that, but just being able to do everything was much better!
I love the way you put it into words "this very much felt like being a kid playing with toys and i enjoyed it a lot, wonderful job !"
That is exactly how it was meant to be!
The physics and all isnt perfect AT ALL, I truly agree that the train feels way too bouncy. The way it feels way too light wasnt intended (I just got tired of stuff not working and that was the closest to what I wanted so just stuck with it) but the mechanic of being able to throw it around WAS intended
I truly appreciate the review and m glad that you got to experience it the way I envisioned!
Thanks alot for giving it a try :D
