yeah, chaotic was definitely the factor I've pushed a lot. Though medium difficulty is kinda lacking on it; it's better to play om hard imo.
Tbh, the achievment system really isn't that hard to implement. Just checking and saving the numbers, really. Since I finished the game way too early and still had a day, I've decided why not?
I'm more than anyone surprised by lack of bugs. All my game jam submissions suffered from lots of bugs (enemies couldn't even damage you in one game!) and therefore get flamed at, but not at this time. Because I didn't overscope this time and disabled all of my unnecessary urges to add more gameplay stuff (i wanted to add a bomb that shot beams diagonally or horizontally upon detonation, like in your game). That's how I should really develop, since there are so many way simpler games than mine and they're unarguably better. So yeah.
I tried too to beat braindead difficulty, but god damn in one wrong move towards a bomb and annihilation. It's all about patience, you must try again and again and again... You get the point.
Thanks for the feedback!
