This was a very enjoyable experience. I like the fact it is a single screen and falling down only makes you restart. The fact there's no lives and the music doesn't get interrupted makes the whole thing more unified and peaceful.
The platforming starts easy and gets trickier. I like the feeling of progression and I'm not sure if I would have liked things to get harder. It was a relaxing experience and it should remain so. So the difficulty felt pretty on point.
Thanks for giving us options to customise bindings. You could actually have the game start with that window just to make the sure the user selects their preference (and they would de facto learn the controls at the same time).
I like the graphics a lot, these shades of purples have a 90's feel to them. The music was nice but maybe a bit strange at times. This was a combination of the string sound quality, the harmonies getting a little bit busy and a pretty loose sync between the instruments which may come from the code (if the loops are launched upon contact rather than launched together at the start and having their volume adjusted). The choice of the soundscape itself was perfect for the game's atmosphere.
I hope you were happy with what you learned and I look forward to your next submissions! Take care!
