It seems that since 26 Jul 2024 cloud saves no longer work. If you don't want to lose months of progress when your computer dies, consider backing up your save files (Best with a proper cloud sync on your computer, but emailing them to yourself now and then may suffice)
It would be nice if we actually had to make more decisions. Not saying it is too easy (especially around 34) but it is never harmful to make a legal move. It would feel more like a real puzzle if we had to consider the order to do things, now it is a bit of just polishing away one block at a time till the board is clear.
Though it probaly won't matter in practice: With upgrades the dragon actually has the lowest attack. So I like to have some dragons but the rest max upgraded riders for maximum killing speed.
Just so you know what you are getting into: The first campaign is much longer than the first goal/boss. You can hit the first boss around day 5 but there are several more before you unlock survival mode.
Tips to deal with randomness without changing feel and main dynamics:
1. Some kind of mulligan, possibly at the cost of an energy or card
2. More predictability in the shop (e.g. allowing re-roll or fake randomness that never leaves you with an unwinnable scenario given optimal play)
After seeing the victory screen, I clicked the top right corner, which results in a complete restart. Please make the path to the Gauntlet more intuitive as this is a bit sad.
Got stuck a while on the screen with the black squares. Not a major problem, but if that is not intentional, consider slightly changing their appearance :)
Note to those suffering from the bug in lvl 7: Even with just 50% you can get the badge, for me the breaktrhrough was getting 100% at lvl 14 (As demonstrated here: https://www.youtube.com/watch?v=wmtHsdeinyE)
A hint for those struggling with challenge 15: yes it may be true that the AI could kill you almost any time, but in fact it doesn't play optimally. Just try a few different strategies (I opened with an attack), and with some luck you should beat him in a few rounds (similar to other challenges).
Note that I got the badge after getting keys Red, Yellow and Green ( Green is right behind yellow, but technically I seem to have gotten it while I already had 3 keys).
I got the key, did the save crystal, and a minute later I noticed I had the badge. I guess sometimes it takes a bit of time? (Was also standing still for 30 seconds, but probably not related).
Perhaps its just me, but though it worked yesterday I get a connection lost today. (Using chrome, it happens after donwloading everything, reconnect does not help)
Using chrome I get a black screen with a dot in the top left corner. This alternate url also does not work: http://targaciej.home.pl/DEMOULO2/ . It works fine in firefox (and based on what I see in firefox, dragging invisible blocks in chrome actually seems to work)
If you cannot stack anything on top, you can often succeed by placing blocks in the middle (thus pushing existing blocks out a bit). This is especially relevant if you are hitting the height limit, but can also help if you need to build your 'support' first and push in balls later.
