I played as many games as possible now. Being a Mac user, the game buffet is unfortunately a bit limited. But I thought I would throw out some recommendations so far anyway:

For aesthetics:

Dissidence by caporaltito

For Arcade fun and polish level:

The Floor is Lava by Slashee the Cow

For finding my weakness(2D in 3D space):

The Screen Pass by Tater_hater

Now I’m off to find some more games! If you can recommend some to me, leave them in the comments! Shameless self-promotion is a-okay!
