So this reminds me of another game I played this entry where you play as a chandelier. It had similar one button controls, but they also had a "speed up" button so the rotation would be faster. I actually like your idea better of having the direction of the rotation change every time you press space, because this actually lets you go through some corners better and faster if you are good 😊
Having said that, there's a couple of things in this game that make it feel a bit unfair. The first thing is that the indicator for where you will jump is often offscreen so you can't see it. And the frog constantly flips upside down to make sure it is straight up. And then, the amount of distance the frog jumps can't be controlled so if you want to avoid a small snake tile, it sometimes becomes almost impossible 😅
I think this could be a good game but you need to be a bit more forgiving to the player. Hard games are fine, but not if they feel unfair to the player.
Don't take this as negative, just trying to give you feedback on how I felt while playing your game :-) I think you have a good idea but it needs a bit more working. Keep it up!
