Honestly the core gameplay is really, really good. Having to balance building up your tower, managing solar plants and turrets, while your core structure slowly sinks into the ground from alien attacks - it really gives me a Plants vs Zombies 1 feeling in the best ways. I did have some issue with the controls, there always felt like a delay when trying to place blocks and it got a little frustrating. I also kept trying to make overhangs with my structure and it took me a while to realise I couldn’t do it. The core design is absolutely there - a little bit more polish (although yeah this was within 48 hours) and I could lose hours to this.
