I appreciate you guys working on the challenges and trying something new.
I'm not opposed to the idea using credits instead of silver if you wanna play for keys but
a) maybe give people the chance to play for gold with silver (sounds weird...) and with the old challenges / difficulty because it's waaaay down which probably most ppl will like. I am amongst those who could only beat a few originally (pretty good at watering / terrible at sickling, fighting etc pp) but now i could beat all challenges even with malus without breaking a sweat. Which is good because your playing with real money but which is bad if you want a, well, challenge.
and
b) the keys. I've played a couple of rounds yesterday and a few right now. I've won 10 keys which sounds good giving I've only payed a buck. However, every single one of them I've gotten before multiple times (I could open a shop with Dungeon Crawlers...) and frankly they're all games I won't be playing in the first place. +my very first two wins were of the same game. Again, we're talking ten cents a key but there are enough sites out there offering shovelware by the dozens for a penny and there's a reason im not buying those either.
Long story short, I'm gonna take a time out with the challenges but will keep an eye on this forum and see how things improve.
Best wishes to all of you and stay healthy! <3
edit: maybe give tokens instead of keys and have some sort of Tier system. Exchange one token get a random Tier 1 game, exchange 5 or 10 and get Tier 2 etc. Maybe including % vouchers for the indiegala shop? Just a thought
