Had some fun

As a free-to-play player, watching ads is mandatory, and each ad is also quite long. For bonus item ads, I think it's safer to watch if at least one of the three options is decent. For planetary weapons, the bee is good. In the early stages of a level, strengthening movement and production is key. For your chosen weapon, prioritizing missile upgrades will make progression easier. Plasma doesn't synergize well with missiles, and the rocket boost makes dodging boss attacks difficult, so I'd rank it low in priority. So, while there's a lot of ad pushing, I surprisingly found some aspects of the gameplay engaging, and I think I'll enjoy it until the title disappears.
