Superb entry ! I loved playing Vampire Survivors so I'm clearly biased. But it must be said that your game is particularly addictive and well functional. I survived for 303 seconds, I don't know if there is an end or if the waves are endless?
However, if I had to quibble, I would say that the "Earthquake" theme is partly respected and could have been the heart of the gameplay (perhaps with spells which can triggering earthquakes ?).
Also I find it unfortunate that you can choose the upgrades with the arrow keys but not control the character with them (I have a french keyboard and have to switch to QWERTY to be able to play your game. You can check scancodes witch Löve in order to avoid the keyboard layout-dependent)
Once again, well done, I had a lot of fun playing your game!
