Feels like you ran out of time on some of the basics but there’s some nice bits here, the alien model in particular looks great. Gotta say though that on game start my audio went extremely loud for a moment like there was some kind of audio glitch and i’m so glad I wasn’t on headphones at the time or I may never hear anything ever again!
Player movement is a bit odd and it looks like you had trouble exporting your 3d level (or cutting the roof off of a stock one?). In any case, you’re getting those basic skills down and you’ve finished a game - so good stuff. And it’s a lot better than some games in the jam, so kudos earned :)
