Thanks for all the feedback. That is super useful.
For the enemy projectiles are you imagining a red circle under them to indicate the collision box?
I agree with the sound effect for getting hit. Some of the other sounds effects still need work as well.
I've got a lot of work ahead of me still, but I'm happy to hear you enjoy the core of the game :)
I disagree about the telegraphing. the projectiles telegraphing is already in the game. its moving towards you at a slow enough speed so i get out of the way. i think that needs to stay exactly as it is. Similar to Isaac or Gungeon i think exploring back is fine as is as well. I really like the accessibility of the game.
I was able to beat the game first try with only taking two damage from the exploding slimes so i think it could be more challenging as you go on. it felt like my damage scaling overpowered enemy scaling. Though for context I am also a game dev, currently developing a bullet hell game, but i thought it might be helpful to know.
overall i really felt the mechanics were good and the demo felt well polished. with some more challenge and bosses i could see myself playing this quiet a bit.
