Thanks for the feedback!
Yes, the sentiment is that the game is a bit too punishing. The maze was a lot smaller earlier on, and the player would simply follow the dog's noises to get a sense of direction. As the maze grew, the dog mechanic basically became obsolete until the final part, which I think we would change if we decide to keep working on this in the future.
We realized too late on in the process (due to lack of playtesting) that the maze itself was way too difficult, and while the teleportation mechanics were really cool, we had kinda gone overboard with the sheer number of teleports. What had started as a mechanic to sow a bit of confusion in the player and prevent them from simply hugging a wall until they reached the end became more a rule than an exception.
I'm glad you found the showcase video so you got to see more of the game than just the beginning. Thanks for playing! :)
