It is not what you expect from a game tagged as "metroidvania", it only focuses on movement/platforming in a mostly empty world and gives the player no sense of progress, things that you would expect from said genre.

The fundamental problem is that exploration is not rewarding and optional power ups do not make a significant difference, since most of them are for combat which in this game is almost inexistent (even the last boss is a joke). Movement is great, responsive and satisfactory, but there isn't much to overcome once you get your mandatory upgrades: your character spikes too much compared to how the world is designed, which includes structures, monsters and obstacles. By this I mean that you can just ignore monsters that are guarding objectives like levers with no effort and sometimes you can even skip platforming sections while being bad at 3D platformers like myself (getting major key in underbelly or other minor parts). In other words, felt like the dev put too much attention to movement and ignored everything else. Art, both music and graphics are good, especially the music.
