Inside an asylum cell dealing with psychological demons is an approach to this theme that's out there but also fits so well in this catalogue of games. The idea of dreadful beasts spawning and surrounding the player definitely embodies the themes of growing anxiety and worsening inner demons, and it's pretty cool to gain, stack, and switch between upgrades throughout the game.
It's in this game loop, however, where I start to notice issues. The most blatant is the interruptive nature of the upgrade segments and enemy spawning mechanics. The upgrade template comes out of nowhere, disrupting the flow of the game, and the enemies can often spawn on top of you with no warning, making for unfair situations despite the demons themselves not doing much damage even in a horde. As for the horde itself, the damage they deal is well balanced for a horde to be threatening, but dealing with them quickly becomes one-dimensional and routine, with many conjuring into a thick line behind as the player automatically swings or blasts them with bombs and center explosives. The upgrade system feels like it should break the monotony, but the overlap on the areas they cover and the lack of enemy strategies extinguishes any chance of that happening.
