Floor 100 sounds a lot of fun, I can only imagine how strong your deck was.
Awesome to hear that you had fun, our first Jam game submitted was really not a video-game and to be able to create something enjoyable is amazing. And yes, we are really proud of this game considering the short timespan we had to complete it.
Now for the excuses, the armor was the last card I implemented so I might have not tested it properly, Makai noticed that on the final hour of playtesting along with the burden of having to spam click upgrade, but since that was the final hour I didn't want to do code changes. So that is a lesson to finish the game earlier, or even one day earlier, to get whole lot of play test.
About a tutorial or tooltips we really didn't think about that haha. Will be writen down.
We wanted to create a boss but we ended up leaving it for last over and over and then we didn't do it.
Tyvm for the feedback and again we are really happy that you enjoyed it.
