not a bad beginning. needs progress without focus. maybe some "hp" at the enemy boxes.

So... Why aren't all turrets sellable? I'd like to be able to start in whatever position I'd like. Not forced to have the first turret in the bottom screen. Why do turrets shoot when there are no enemies? Why don't turrets aim? The burst upgrade isn't a useful upgrade. Its a negative upgrade. Buying new turrets actually hurts you because enemies travel towards the new turrets that are un-upgraded. Enemies need health bars/stats. I'd like to have a tooltip for upgrades showing what the new value would be. Range also means nothing since I can just help my ability to gain points by buying more max enemies. There is no reason to ever buy a turret. Different turret types should have different effects not just different base stats. Multiple enemies, damage over time(dots), multiple enemy penetration(LASER), explosion radius, stacking damage. Whatever.

Prestige currency/system. Reload time plus the turrets always shooting hurts.

Just a few things to think about.

This is not ready for public release at all. The costs are all over the map, the enemies do no damage and just hump you like it's a mass cube orgy. Also there's a glaring bug: If you buy all Basic turrets at the start, and then upgrade Damage for each one, the first turret upgrades to 2 damage, the second to 3, the third to 4, and so on.

Great start. It would be nice to enemy hp. Slow at the start but once you focus on upgrades to single tower, goes ok. Any chance to give enemies a bit of color depending on stats.

Also, Sniper tower has zero value since enemies move so fast they swarm the tower before shots can be fired. Range means nothing. The base stats for all towers need a serious rework. not just plus or minus one value.

Also, selling a tower should give you money.
