It's an alright tower defense incremental, but it has some problems. For start it's difficulty is far too easy to a point u wont lose and go back to wave 1 unless you are afk or doing something wrong. Second is the unlocking cost of new turrents, the shotgun cost at 50k on wave 10 is a big high but affordable and it's a good weapon to get at that point. But the sniper at wave 50 costing 200k and having almost no initial damage and with it's initial upgrade costing over 2k to 3k for a small amount of damage increase is far too inferior to using that gold on one of the two other guns cause their upgrades will be far cheaper and provide more dps considering all the fire-rate/crit you already got. Third is that the field of view/battle area is far too small, making the dificult of the game be the enemies that spawn close and move fast, but even with that the difficulty like said early is far from relevant, i only took damage on some of the early waves and none after till i quit on wave 65, maybe if the field was double or triple the size and enemies had 3 or 4 times more health it could become better, specially considering that the shotgun splash loses damage from distance and the piercing from sniper loses it's value when enemies just spawn far too close and die instantly to the other guns. If the difficulty was increased and instead of going back to wave 1 you unlocked some sort of permanent upgrades/prestige/rogue lite thing it could maybe become better, then the difficulty could be increased a lot more than what it is now.
