Very cool! Good to see another Godot entry. The main issue I had was the audio. The shooting sound can get a bit annoying to listen to after a while. I recommend changing the pitch of the sound randomly whenever it plays. You can do so like this:

(path to audio stream player).pitch_scale = rand_range(0.9,1.1)

(If you use this you probably wanna put it above the line where you tell the audio stream player to play.)

I Had SOOO Much Fun with this game. I dashed around like a mad man slaying monsters left n right and by the end I was sad I had to be done lol great job. loved the level design and the enemy variety and of course dashing around like a fool lol. 

Nice music and effects! Excellent game!

So far the game i've spent a little longer in, quite the hard little project, but definitely has the potential to be a really fun little game.

I think the text loading so slowly and being unskippable is a little annoying, but that's my only bother with the game so far.

I also like the items addition, the second level i got absolutely minigunned down, but otherwise had fun.

Nice submission
