I feel like this whole "Lab-rat character running experiments for omnipresent overseer" thing has just been done to death. I can scarcely recall how many games I've played that have the exact same setup as this. This game feels very derivative to me, and as such I can not give it a higher score.
I did actually spend an hour or so playing it though, and I had a few minor problems.
First off, there's no sense of story progression. The character exists only to be killed by traps (you seem to really like spikes), and we never once learn where he came from, or how he got to be in his current predicament. All we know is that somebody somewhere is testing a brand new syrup that brings people back from the dead, and the character is their most recent guinea pig. Nothing else is explained.
GOV has no character, and basically exists only to taunt the player, or tell them that "The last guy never made it this far/ died horribly." All we know is that he/it runs experiments on the life syrup, and that's it.
Secondly, the music was a problem for me. I look slightly to the left, and see that there are only two songs in this game. At some point, they just bled together, and it just sounded like one long, repetitive chiptune-- which began to grate on my nerves after a few minutes of play.
I know a 2.5/5 is a bit hard to swallow, but hopefully you will take what I say into account, and improve.
So, summing up:
-- Flesh out characters and story
-- Add variety to your music.
