I get the roguelike intented design, and I get that too many permanent upgrades can ruin the gameplay, but for god's sake, that doesnt excuse not getting any rewards during the run for beating a BOSS, other than the chance to play a frustrating minigame that most often will have you spend all your money with nothing to show for it. Give me 2 stat upgrades for beating the boss, for the love of god, or let me pick 2 skills, since most of them absolutelly suck balls, making me even wonder if buying them in hub is even worth it, as it'll just dilute the skill pool. Or, I dunno, some dialogue after or in camp?? At least that?? It feels empty.
You never feel even 0.01% better after spending a buttload of coins on items and skills, let me at least pay for permanent reroll in the beggining, or if thats just too much, for an additional option to choose from, or a measly item that you get from the start, or one extra stat upgrade in the chest, and since I think there is only one chest per map, it would be only an extra stat upgrade per map. Anything to feel 1% stronger than 15 hours ago...
And what does the skip to the boss ticket even do? I used it before a run and it did nothing, I thought it was a way to get to the boss at the beggining of the run so you can quickly get to the second level...
