Ooh this one is really interesting, I always like the concept of selling your soul for power.
I do think sticking to the limitation this time is actually limiting your game!
Having the Demon Meter immediately game over you is a real shame, because I think there’s a lot of potential in having both playstyles? Like, imagine if you could still have a really high demon level, but instead of immediately dying, you can just get one-shot! So it’s more of a high risk and reward rather than risk (game over) vs only use the normal attack.
I also think the demon meter is way too strong for how much curse you inflict upon yourself. I did a playthrough where I only used the right click attack and won the game with a lot of demon meter left to spare. It also one-shot a lot of enemies, if that’s what you intended.
Some things I did like were the varied enemy designs! The animations were neat, I like that you had the skeleton’s melee attacks visually distinct.
One thing I can really appreciate is the absolute clarity of your levels. I can see where the enemies are, what projectiles are going where. It’s sososo important that this is clear to the player (unless intended by the designer) in this kind of game. I love how readable this game is! One veeery small thing is I had trouble knowing where to go after the one spiral enemy in the big room, but that could be fixed easily with a compass/background decorations/etc.
Fun game!
