Out of the 70 games I managed to play so far the following 8 caught my attention based on the ratings categories:
Overall: Tendril

A deliberate pace sets the mood for this unique game with a one-button mechanic that rewards patience. The tension that is created as you try to weave through an opening and the relief once you’ve cleared it is extremely satisfying.
Innovation: SDFJKL

An original control scheme that makes for a very interesting Spider-Man-like experience weaved with a tale that puts the abstract graphics into context with every varied level.
Fun: Super 1-Bit Space Arena

Single player Smash Bros. with guns. In space. Enough said. Seriously though I kept coming back to this for more.
Theme: (Follow the) Line

Simple yet elegant graphics, one-button controls, and no audio. Minimalism to the core.
Graphics: Somsnosa

Outstanding artstyle with mind-bending abstract/surrealist environments and crazy creature designs give a fresh look to this entry that really sets it apart from the rest.
Audio: Wandering Darkness

This claustrophobic platformer has compelling level design and it keeps you company with a number of varied tunes that are not your typical fair.
Humour: Staring Contest

Minimalist comedy. Couldn’t help but laugh at the voiceovers and absurdity of it all.
Mood: GHOSTS

The tension is palpable in this game. Every element seems to reinforce that mood, the crescendoing music, the increasing light and thus greater threat level from the enemies as you try to find the exit.
PLOT TWIST: Worst Game (stealth shameless plug)
