Good looking and pretty fun even with the placeholders but a little buggy:
Neither the shop or level up screen never showed up for me and twice the counter said 0 demons but didn't the portal didn't spawn.
Also idk if it's intentional or not but there's a delay when you switch weapons before you can switch again which was annoying when using the mouse wheel instead of 1 2 3
Regardless, the potential is there.
Cool music too.
