Very solid game so far, I like what it has to offer and how it plays, it is pretty unusual because rather than being the fast paced action game or being more like mario, it instead reminds me more of I Wanna Be the Guy because it relies on being careful and using calculated manuvering, because a wrong step can mean death, at first you learn this the hard way but afterwards you know what to expect and what to wait for... of course it's much fairer than IWBTG lmao. I mostly died because of my fault, because levels have their trick or bosses have their pattern, so points for balance.
The graphics are minimalistic but I think they work in the game's favor, having the best viewing distance in sacrifice of graphics, and even then they are appealing enough, of course it happened that I did some jumps of faith but those were my fault.
The music, even tho it is a bit inconsistent over stages, because of the changing soundfont, I found some worthwile tracks and some that I found very good, nothing much to say here.
Overall, it's a good game and it has a lot of potential, so good job.
