I love the spooky theme of this game, really fits well in every aspect!
The gameplay is also no joke - The player hitbox is super clear, the firing rate is really tasteful, the hit feedback of enemies and their death animations are amazingly satisfying and the enemy patterns are really inventive and full of personality. The death animation is also really well invented. But who can forget the "IMMA FIRING MAH LASER" moment when you stop firing for 10 seconds? SUPER satisfying, and amazing use of theme!
The only complaint I have is with the first warning of the game about gamepad controls. First of all, this is a jam, which you should consider that most people are probably using a keyboard, so saying that the game is gamepad only may scare them away (which by the way supports other controls either way). In addition, there is too much text in that warning to read in such a short period it stays, had to reset the game 2 times to read it properly, also the font does not help much for clear understanding...
One thing you could do to prevent that, is to do it like the Yakuza games do for their ports on PC, on Yakuza 0 for example, the game starts with a screen with a gamepad image and below it is written: "Real Yakuza use a gamepad", which it implies that other controls could be used but the best experience is achieved using a gamepad, it is simple and short but conveys the message well.
