Praise the orb and praise your feedback!
The gold thing is new, thanks for catching that! The level 4 thing being broken is also a good reminder for me, i think i just forgot to put some sprites in the right folder and now it crashes when looking for them. Truly my fault and will be fixed today! Crash on death is another bug i actually knew, but forgot about it (will also be fixed today).
Now the regular/stronger goblin distributions are a bit random, but maybe i really should disable the basic ones for level 3+. This wouldn't be that bad and obvious if i had more enemies in total and not just the two.
Level 2 (or any for that matter) changing colors is new to me, i will investigate this.
The uniques are quite rare, maybe i will up their droprate a bit to make it easier. The boss is still waiting for some animations, but i may just drop him in with some placeholder stuff since i will need to adjust things today anyway.
Apart from the bugs and inconveniences, how was the performance for you, especially in level 2 and 3? Im not sure how taxing the color replacement for the goblins is at runtime, the laptop im developing with at the moment is a bit weak and running multiple programs makes this fluctuate a lot for me.
