I'm writing my thoughts as I play, so it may seem like a stream of consciousness.
-The simple pixel art style reminds me a bit of OFF.
-The soundtrack is alright. It doesn't really stand out to me personally.
-I had to read the review below to know that I got stuck after collecting the crystals in the wrong order in Stage 2. I'm fine with the way the game introduced some basic mechanics by show-don't-tell, but here it is necessary to give direction to the player. Once the text fades, there's no way to bring it back. And, it is only in Portuguese, which presents an even bigger problem for any players of the game who don't speak that language. This is where having visual instructions would be ideal.
-I would like to have an option to have the game be windowed, and an option to restart from the beginning without having to close and open the game each time. It took me a while before I realized making myself die could make it reset instead.
-That said, I did enjoy the puzzle mechanics and once I saw the pattern, I began to think in terms of that.
-Agreed with hythrain about blind leaps of faith. If I hadn't seen that post, I'm not sure how long it would have taken me to realize that I needed to jump off the edge for a couple of the stages.
-Good concept overall. Controls feel kind of hard to work with personally given how fast the character accelerates.
Overall, the game needs some polish but it's a pretty good concept overall.
