You gave a really good suggestion, I liked it. I made the game quickly just for the jam, so I didn’t create that many levels.
By the way, can you tell me which game engines you use, how many jams you’ve participated in, how many you’ve won, how many you’ve lost, and how many you left in between?
Your game is generally pretty good, but the attacks just keep missing the monsters, and the monsters deal a lot of damage, making it quite difficult. It's also hard to dodge many attacks, and then there are the flying bat monsters, which makes it even worse.
