Enjoyment 3.5 rounded up to 4: I move. So. Slow. And there is so much nonsense so quickly.
Execution 4/5: Everything seems solid enough. I think there are some questionable design decisions about movement speed and upgrade availability. And at risk of decreasing the fulfillment of your interpretation of minimalism, I think a button to close the popups might have been good. Awkward to pull out the mouse for just that part.
Sensory 3.5/5 rounded down to 3: Serviceable music and sound all around and the pixel art was charming as it goes! Music wasn't my thing as much.
Metroidvania 1.5/5 rounded up to 2: There is a bare minimum of utility gating and exploration. This isn't really in the genre criteria for this jam, to me, as big-tent as it normally is in these ways.
Minimalism 3/5: The theme interpretation is met, and the controls are minimalistic but that is ...not really doing it for me in terms of theming vibes. The game doesn't feel minimalistic for all that. Sorry!
All that said, I have followed you so I can see your future rogue-lite endeavors.I do think you have some good potential in the 'defend your base' or Vampire Survivors or similar top-down action-roguelike or rogue-lite space and would like to see more of your work in that space.
