Indeed! I also think this combination has some potential but its an incredibly tough challenge from a game design perspective. Both vampire survivor and magicka are incredibly well built, very complex games from a design perspective. I'm considering doing away with passive weapons altogether and go pure active because they can't really seem to mix properly. And frankly the combos are not fully implement so there's hardly any benefit to cast more than one glyph, as can be seen by reviews about everyone spamming a single ability. The selection of abilities needs a rework as well, I chose them based on actual Vampire Survivors weapons (like the dark circle being a direct analogy to pentagram and hex flask is just santa water). But that selection doesn't really seem to work out when the player has full control over what weapons they get to use. Not to mention I didn't have the time to lay out an ability matrix to figure out what effects what combos would have to then adjust it. So when you cast more than one glyph all you get is a stat boost which is hard to tell unless you're actively counting damage markers.
I'm still pretty happy with how it turned out especially considering this is the first game I've actually made, I spent years learning about every backend system that goes into a game engine but never really put that together into an actual product before. For example, the outlines you see are made by reading the depth buffer, and that required me to create a custom depth buffer directly using opengl commands without relying on raylib, its also the reason I put a giant warning on the description saying *please let me know if you encounter any graphical issues*. So far the only failure I've seen is on a 15 year old computer that just refused to render the game.
I think I will definitely try to polish this into a better game after the gamejam, the mechanics will need a lot of thought to actually nail down. And I need to make it so players can't live indefinitely by just walking around. Because thats something you can do right now if you're good at herding.
