This kept me playing a good amount of time, I enjoyed every second. Is very fun to play the mechanic is really great mixing tower defence and vampire survavors with the terraria minigame. A great combination that works. If you polish this you have a really nice game.
The only two problems that I encountered were the audio(multiple instances of the same audio played at the same time exploding my headphones in the process) and the lag, with 15 or more enemies i couldn't reach 30 fps.
Nonetheless great work!
