This is a cool and unique idea for the theme! I really liked it and played all up to level 30!
I was shocked to see how many levels there were and from the looks from your screenshots there could be more traps, I would love to see them. My take on this is that you shouldve added the other traps sooner so that it gets to be introduced early so that players will keep playing to see the next traps
Also loved the blood splatter and also the sound effects, it really added so much more into the game!
Overall, its really really good, it felt like i found a hidden gem among all of the games on this jam!
