A very clever use of the theme, and a pretty fun game to go along with it. Usually games like this have a tendency to get too easy, but I think this one's difficulty curve was alright - I got to around day 10 (not entirely sure, it should show you on the death screen). I feel like this is a game where you're meant to make a base, but with how zoomed in the screen is, how bullets are stopped by walls (I recall) and how slow it is to collect rocks, it doesn't really lend itself to base building, with my tactic being to just collect stone and place spikes in the way of the enemy. I think the potential could've been bigger, but I still played until the end, so well done!
