My feedback for Bloodbot:
What your game does well:
Your game has all the hallmarks of any good top-down space shooter. The art and graphics complement one another.
This is a simple interpretation of the theme 'inside out' but works.
Enemies and power-ups are balanced. There's no enemy too difficult and power-ups last a good amount of time for players to make use of them.
What your game doesn't do well:
The game lacks enough feedback when the bloodbot takes a hit. The flashing is there, yes, but the player will only know they got hit if they're looking at their ship. Most of the time the player's eyes are on the enemies.
The theme is baked into the game's aesthetic, but that is the only part. The entire game, as an abstract system, has been done so many times. I would have liked to see you incorporate the theme with the player's actions or the behaviors of enemies/objects/etc.
Areas of Opportunity:
If you're approaching the theme as the game's setting, and the bloodbot is inside the human body, perhaps a way to integrate the gameplay with the theme is to consider the health of the human you are shooting lasers & destroying viruses inside of. That might add an extra layer and affect the player's choices. There are, of course, other ways you can approach this.
I hope this feedback helps!
