Stylish visuals, I like it.
- I don't think that the basic trooper enemies should be fast enough to outpace you and catch you from behind, unless you've chosen options that slow you down, or it's much later in the run.
- The options presented on level up feel both too complex, yet too simple at the same time. Too complex, because each option presents multiple stat changes with various trade-offs, yet too simple because they are only incremental stat changes, nothing really game-changing.
Anyway, good stuff, keep at it.
