Nice job, love the concept.

Quite difficult, I couldn't pass the second level so I clicked with frustration until I started skipping (winning) a level everytime I clicked. I think that was a bug xD

Oops, sorry, copied two times the same link. I should proof-read everything I post, I make lots of typos

Don't worry too much about learning lua. I didn't know it when I started with löve and didn't have a problem with it. It's really easy, if you've programmed before and know three languages it won't be hard. What I suggest very hard is to look at the wiki. Specially some of the tutorials like Hamster...

The usual first approach to collision resolution is "if the player enters a wall, push it out quickly". It works, but that makes it really ugly. What you want is to, in one only function, decide if the player can move or not. Doing so, the player is never "inside" the wall. You m...

When the list is empty you have to return true, so that it doesn't break all the ands made with the keys.

It crashes when you are on the exit and try to calculate the way to the exit xD Otherwise it works flawlessly, nice job

Oh, sorry, I misread your first question. Yes, setX() will "teleport" the object. The most logical way would be to apply a force (with applyForce or applyImpulse) to the body. The x and y components can be calculated just substracting the player position to the object position and normaliz...

First thing: You can use https://love2d.org/wiki/Shape:setMask to set which shapes collide with others. Second: Using https://love2d.org/wiki/World:setCallbacks you can set what function will execute when two shapes collide. There's an example at https://love2d.org/wiki/Tutorial:PhysicsCollisionCall...

The perfect excuse to retake projects, I'll see what I can do

I figured this out when playing Super Mario War four people on the same keyboard, when the player on my left sprinted I couldn't move to the left xD Very fun game.
