I get a compile error when I download the tic file and try to run it in TIC-80.

Nice game. I really like your graphics. Tiny pixel art is such fun. Thanks for making a fun game.

howsabout more bosses and weapons? but still, good work, you're great

Sure! I actually planned a lot more for the game, but the 10 days of the jam flew by haha. I want to add new bosses and weapons now that the jam is finished though


What an exciting game! i finally beat the boss with the third weapon, it was quite tough! Image

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!

Nice that you were able to beat it and thanks for your comment! :D Yeah, I’ll surely make a post-jam version. I want to improve the boss’ AI, animation and also recreate the win screen, it was a complete improvisation in 20min for the jam.
