thanks a lot for playing, and the feedback is welcome and greatly appreciated! :) I didn't even think that 7zip could be an issue but I suppose you're right... this was a first game jam for both of us so we messed up our presentation a little. for instance, we forgot how to make the game playable in browser and discovered that it required merely a couple of clicks right after the deadline lol. same goes for the tutorial. we will continue to develop this game and we're already thinking about how to introduce a player to the mechanics seamlessly, with no text at all.
TLDR, we both were panicking for the last two hours so yeah, it is unfortunate but it is what it is. time constraint is punishing in that way. but once again, we appreciate your kind words and the feedback! and you can bet we are not gonna use 7zip next time ':D
