Simple concept, nice presentation and challenging if you don't write stuffs down.
The theme is used in a great way. Good job.
I really like the "Enter the Gungeon" feeling. The enemies are fun to kill, and every one of them offers a different challenge (I hate that necromancers they are the real deal).
I enjoyed the gun play every weapon has something to offer. The core game is really fast phased and i loved that. Great job!
