Cool game, I would like if there are a little bit more gameplay like some puzzels or moving stuff to get the orbs.
The visuals are very nice minimalistic, but sometimes it is not very clear what is I can walk though because its a 3 dimensional object (like the fance in the 2nd part), maybe they could have a sligly different tone.
Also I got stuck sometimes on corners, maybe the collision of the player could be rounder and smaller.
Overall I love the retro vibe of the game, it feels like an old arcade game! good job :)
