Pretty nice! It was hard at first but then I found that the best unit to build was the most expensive one (they never seem to die...). Hotkeys for selecting a unit to build would be a nice extra

I found difficult to understand what the ennemies was shooting for, and I think the game could be improved with some different kind of units, so you can have another strategies than "put the most expensive one as soon as you can affort it". I did'nt spot any bug or any issue, the game runs smoothly, and the controls are ok!

Maybe you should let the player run the game at the resolution they want, because on larger monitor, you have to pick the unit quite far from the center of the "board".

Thanks for sharing your game!

The game is very difficult to understand. The way the game world is laid out makes it impossible to tell where enemies are going to shoot you from, and once the shooting starts it gets even more confusing with all the projectiles. I could not for the life of me figure out what my turrets were shooting at.

I think you should make the enemy ships appear gradually instead of having the player completely surrounded right from the start. It seems like you've got a good foundation for a tower defense game here but the level design brings it down, which is an interesting problem to have for this type of game.

Since the towers look like trucks, maybe you can let the player issue move orders to them. If you have a bunch of towers on one side of the island and enemy ships start appearing from the other side, issue a move order to try and intercept. You can get creative with the tower mechanics since they arent exactly towers and create some unique gameplay

Nice game bro!
