I made a game that im currently making a balance patch for post jam because the difficulty is a bit upsetting.
It is not quite "git good" its more so a mix of that and there is alot of rng as it stands since I made a card game. I have plans too fix it, but to put into perspective how off the balance ended up being while testing I could get to level 7 out of 10 (so I knew it was hard) but from the feed back I got people could only get too level 2 - 3, which is sad since the theme changes at level 4, 7 and 10 but very few people have seen it.
Part of it was defiantly intentional but I do not think its very easy to learn the little optimizations that make your runs smoother. TBH I do not think its possible to beat in its current state the last levels have little to no testing...
My brother did actually get too the final level after I showed him a exploit I found while balancing it .-. but thats going to be patch out
