I got to level 100 and am currently #1, and this game is definitely a time waster, but a good time waster. It can have big lag and has several bugs that I'd like to see fixed: 1) Bullet multipliers have a cap, 1000 b/s gun takes 10+ sec to kill 3000 hp boss. 2) If you kill to many or all of a future wave, you may be frozen in place, or you will be pulled through the last little bit and game over. 3) Enemy can't be killed immediately after they split. So a 8 splitting into 4s takes to long. 7/10

1 sitting of 1 hour and 54 minutes to be the top one in this game with the score of 7276518 (without the ads). It is online so you could watch ads and it won't let you play properly. Thanks to AdGuard I played properly without ads

The ad to gameplay ratio is way off for what i look for in games. Ads before and after the level. Ad always at the bottom of your screen. The next level screen has an ad in the background. 4 ads per 1 level is insane. Add on top of that a fake leaderboard to push you to play more, the boss fights are over quicker than any of the levels. The only merit is that the gun creation while basic is a somewhat interesting puzzle. Add on to that the satisfaction of using it. Solid idea. Poor execution.
