Thanks for the reply!
Yes, I need to work on the teleporters introduction, I will publish when it's ready.
Hmm, about being restricted by one block I don't think I'm that restricted. I made the game because I saw the potential in it and the idea of the teleporters came because I thought about a platformer with only one platform. I have a couple of ideas tho for making levels with 2 or 3 blocks in it, but I don't see my game having a bunch of blocks because then I don't see how the teleporters might work and make sense.
About the ticks, yeah, it might be a bit fast, but also if I make them slower it will make the repetition function obsolete, because then its too simple to get to the door/portal in time. What im planning is to make the experience and learning slower. In the begining the player cannot edit the teleporters and they will be set up in a way that requires the player to both think and react fast, so the player gets the chance to train before the real puzzles. Also I'm thinking about adding a 4 tick teleporter.
Yep, there is a huge design playground in the idea and that's why I really wanted to create the concept and to see where I can go with it. I didn't know how much time it will take me to do all the stuff since it's my first game jam. Here you can see my full playthrough and check out all the levels you might not got there yet (I edited the video so it won't be too long. In real time I've played about half an hour):
