I've enjoyed seeing the rise and fall of mobile games - and the effects it's had on the wider gaming landscape. As the mobile market has slowly shifted towards gacha and idle mechanics, a lot of the enjoyable precepts of "lunch break gaming" have become heavily integrated into the indie landscape. A lot of these sorts of games though, being roguelikes, are a bit too mechanically bare for me. 20 Minutes is a breath of fresh air in that regard; staying simple, but not abandoning kinesthetics.
It takes very minimal upgrade trees: small boons to your gun, or elemental abilities; and ends up creating a very synergistic playground where almost every upgrade feels at least somewhat useful. Many games seek specialization and punish generalization, which is fair for balance but requires a high amount of options. There are problems, especially with visibility, but I've very much been enjoying 20 Minutes in comparison to other similar recent games like Vampire Survivors.
