Looking at the thumbnail I didn't think this was going to be a pico-8 game. You really managed to create e unique look with the restricted palette. It almost got some zx spectrum vibes, and I'm all for it!
Having to duck behind rocks and watch out for cacti coming up from behind kept the gameplay really engaging. The special move is also a great addition.
I think the theme wasn't super clear, I guess the player is dealing out the penalties, but would be cool to maybe have that play a bigger role in the gameplay.
Definitely want to play the full game, the UI is hinting at some collectables or dialogs happening which really peaks my interest.
