A few problems. First, levels are random, it doesn’t get progressively harder or anything. It’s also pretty much impossible to finish reach the end of the game. The cash system doesn’t offer any benefit other than buying a different gun at the start, the other 2/3 being locked behind an ad. The entire game is as oriented, showing you two ads in the start screen, often an audio ad while playing, occasionally a pop up ad in the background while playing, and after every game ends there’s an ad. Helpfully the game gives you a nice remove ads button behind a paywall, very nice. Add better progression, tone down the ads, maybe the more fun side of the game will shine.
