This game reminds me of my game. Its pretty difficult. I personally believe the easiest level was level 2 as it did not have any obstacles and was an empty room. I think that should have been swapped with level 1.
The functionality of the game is cool. I see how it automatically shoots which is inconsistent at times. I also notice that enemies die usually within two shots but sometimes it varies.
There is a lot of potential with this one and reminds me also of that vampire game, I think it was called "Vampire Survivor"? But yea, very cool concept. The art style matches really well. Just wished there was better progression and a tad bit more consistent.
Overall a great job!
