The core mechanics are solid- it's unusual that you literally hit enemies with the stick but it's pretty fun once I figured it out. I couldn't remember the dash key the first time around, but the second time I did and it worked well. The idea behind the theme implementation is really interesting, though...
The game is really RNG-heavy, which I hadn't expected and wasn't a fan of. I made it to the boss the first time around, ran into some kinda glitch which made my character fall to the bottom of the screen and become basically uncontrollable, and lost. The second time around, I got bad modifiers including "double enemies". I'm not sure if it was that one or another RNG thing but I ended up facing off against an absurdly large amount of enemies and didn't make it past that round.
The graphics and audio aren't good, per se, but they're about right for SBIG Jam.
