Thanks for playing the game :)
" Right now game seems to be too easy. In just a few minutes my fire rate was so big I could just stand in one spot and rotate and no enemy would be able to hit me :) "
We were doing some leveling/evolving system changes in the last few hours, and using a bunch of non-linear formulas that scale over time. Our math was off somewhere, but sadly we can't change it anymore.
"Also no not sure how leader board worked. Did I miss the place to enter my name?"
You didn't miss it, we tried to add this in the last few minutes of the jam but failed to upload in time. The game uses loot locker's leaderboard already, so there's unique player identifiers on the server - we just don't display them.
