It's Undertale!! I enjoyed the puzzles but I will say, the background music loop is a bit off putting because of how short it is, and I think playing it on itch was a little weird coz the resolution is too high it wouldn't fit on my laptop screen perfectly (or at least it felt like that). I also agree with the first comment how the controls being a lie would turn people off from playing your game, coz I did feel a little frustrated even knowing that the controls might be different based on your description coz I thought the game wasn't working for at least a few seconds. I did very much enjoy the hidden trails and all that so props to that!!
