Super on theme, and the art and music are great! The platforming controls feel really good, which is something that's usually lacking in jam entries. Very satisfying to land on a platform. Generally the level of polish is super high, especially the animation and the game over screens. Which, by the way, I saw a lot of, lol. My big piece of feedback is that it's soooo hard to aim your grenades. I think I successfully killed only one little bomber enemy, and that was purely by accident. Allowing you to use your mouse to better aim the grenade would be a big improvement. Also, unless I missed it, there was no way to see what your actual chance was for finding a portal, so that would be nice to see on-screen as well. Overall, great work!
