Thank you for playing! Unreal Engine is the engine Frits & I are most comfortable with using because of our study. We had to use an older version of the engine from a couple of years ago that still supports web builds haha. It's always interesting to try and figure out ways to make 2D look good in a 3D engine without performance issues.
We really appreciate your feedback. We'd love to look into some extra balancing and polish for after the voting, so this is great!
