First of all, good effort! You made a game! I don't want you to forget that and not be proud of your work!
Stop reading here, if you are happy with that! However, if you want some honest feedback...
There are a lot of issues that I have with this. First, it is very very hard to see what is going on. There is not enough contrast between the game objects and the background and, well, everything really.
I gathered that the 'gimmick' of the game is that the controls keep changing in surprising ways? It is really frustrating to play and again, very hard to tell what's going on -especially when you are in places with long stretches of bare ground since you can't tell if you are moving and in which direction. I would have given more indication of how the player is moving, maybe even give a warning when the swap is about to happen (a 3, 2, 1 countdown or something)... or I probably would have tried a less-frustrating gimmick to the game...
It is very important to always give the player clear and actionable feedback in order to create a fun gameplay experience... I hope you can look at this as a learning experience and keep making games with these things in mind!
