I bought a relic while having 228 crystals, the relic cost was 128, i had still 0 crystal after this one buy. Seems fishy. Each rebirth i'm losing level in some of my relics level, which i don't understand why.
Would be nice to have an option of sort to auto-start while ignoring the timer, timer that seems to have longer waiting time the higher you go.. what's even the point of doing that?
i don't seem to win my normal amount of resource in production before i enter the production panel. So each rebirth i intend to use any i've to go there immediately after rebirthing to produce the normal amount.
i feel like the game isn't very rewarding when you try to push to the higher waves, i would gain much more rebirth point by just rebirthing every 30 or so waves than by going to the 300th range.
Would be nice if i could replace a mastery by another one that would be more useful instead of keeping one that happen to be "useless" to me. Aka i don't use the grenade at all.. but i have the mastery corresponding to it, i'd like to sell it or scrap it to replace it by something else that i would actually use.
Previous masteries aren't useless as they help you unlock upgrade for your related power. Level 100 in throwing knifes give you a upgrade to your active ability for example the augment the time it stay active by 10 seconds.
