What an exciting game! i finally beat the boss with the third weapon, it was quite tough!
Graphics and music reminded me of Environmental Station Alpha, gameplay of Space Impact. The level had a nice ebb and flow difficulty curve, and the three weapons gave a reason to try again after dying.
This is surely a welcome addition to the fantasy console scene (and the first game I've seen made with a pre-release v0.80 of TIC-80!). I'd like to see a post-jam version of this one day!
