One of the best looking main menus I've ever seen for a Jam game, and the visual elements in general are fantastic.
I did have some problems with the way the aiming works, the fact that it keeps recentering makes precise shots impossible and the railrods don't seem to always hit the centre of the target icon, going slightly down and to the left a lot for me. When your enemies are so small, this can be quite frustrating.
I know you ran out of time to add sound. Which is a shame as it's hard to tell where enemies are without some kind of audio or visual indicator.
Still the game functions and runs very well, I found no bugs and it's a great accomplishment on a technical level.
I'm looking forwards to seeing how this project progresses in the future and I hope you guys feel proud of what you've achieved.
