Preface
The rating is based on my personal preferences alone. Generally, I'm pretty open to new experiences, but I prefer games where lots of things happen. I tend to be a harsh critic.
I have not finished the game yet (I'm stuck at the dash stage)
Gameplay/Fun
Pretty enjoyable (you can go real fast), but slippery. Also, you can fall out of the level at times - let the player die organically (e.g. put some spikes underneath the level).
Art Style/Visuals
It's obvious that you put a lot of effort into the art, and I appreciate that, but it clashes in places and loose ends can be seen, like in the corpse scene.
Audio/Sound Design
I mean, the song is good, but its tone hardly fits the setting. Also, it's just one song.
Innovation
No innovation to be seen.
Theme
You're completely alone, so the game is accurate to the theme.
Verdict: Good game.
RATING IS SUBJECT TO CHANGE.
