Spooky!
Fun game, and very impressive that it was finished within a jam. Graphics and sound were top notch, and it ran at a smooth framerate.
The enemies didn't feel distinct enough to me - I dealt with all of them the same way: run in a line until they're all lined up, then spookblast em.
Speaking of the spookblaster, it felt like any level-up that affected it was clearly the choice to take. The other upgrades didn't feel as impactful, partially because they all depended on deployable equipment you didn't always have.
I never made much use of the sticky grenades or force fields (whose behavior surprised me a bit - was expecting something that helped with my health.) I made some use of the turrets, which I fully upgraded after the spookblaster, but their use seemed anti-syntergistic with that of the spookblaster, which required you to move in a single direction for a while to line up enemies, whereas the towers required you to stay in a single area for a period of time (which was dangerous.)
Very nice work!
