Hello, thank you for trying out game!
Yes, we have also received feedback from other players that the ranged weapon feels uninteresting, and I do agree. During development I spent much more time fine tuning the sword to make it feel good than the ranged attack. We did have a different enemy type, weapons, upgrades, and a boss in mind while developing the game, but we couldn't implement them due to time constraints.
As for the art, I agree. The art for the environment was honestly rushed, and on top of that this was our artist's first time doing any pixel art. If we properly continue the game, we plan to redo all the tiles and sprites
Thank you for your feedback and for playing our game!
