The boomerang is definitely a bit overtuned in this build. We are planning on decreasing its hitbox size, but that's a little farther down the road.
We also thought the repeater felt a bit clunky after this build, so we introduced backpack reloading, which will passively reload whichever weapon you aren't currently using (sadly not in this build).
We are slowly introducing more upgrades with each new update! I believe our most recent build has 29 to choose from. This build is the Alpha build I mentioned above, which can be accessed by filling out the playtesting form on our Discord.
Thanks for the feedback!
