Hey, thank you so much for playing! Reassuring words like yours are what keep me working on the project, and I intend to take your criticisms to heart!
I'll be releasing a build by the end of the month which should hopefully address the shotgun and dash feeling underwhelming, along with fixing some jank and adding a lot more content.
I hope you'll come back to the game when more is added, and it'll eventually reach the potential you see in it! :)
