This is a tower defense game that does not use a grid system. It does not mark enemies' paths. It lacks essential quality-of-life features. And it's coded in such a way that the enemies are inconsistent in their behavior each time you start a wave.
For instance: I want to place a wall to block a doorway. The doorway is larger than the wall, meaning I need to make sure to position the wall in the middle of the doorway. There is no indicator as for when I've successfully blocked off the pathway versus when I've left too large a gap on one side or the other for the enemies to pass through. This would be solved with a live-updating enemy path indicator, but that doesn't exist in this game.
So I place the wall down, only to realize it's not in the right spot. If I notice the mistake quickly, there is an undo button, but that button is inconsistent and doesn't always operate properly, and I cannot pick up anything I put down. Meaning this wall is stuck in the wrong spot and I have to either restart the level or load a save (you only unlock the ability to save after level 8 for some reason). This wall being a headache to place correctly wouldn't be a problem on a grid system, but this game doesn't use that. (Larger walls, smaller doorways, or a geometry snap-to system would also mitigate much of this problem.)
So I've finally set everything up. All my traps are down, and now I save and release the wave. Only whoops, something is wrong, so I load the save... but I cannot undo anything, and I cannot pick up anything I placed. And because we only get one save slot per level, I am forced to restart the entire level, placing everything back, just to correct the placement of one trap. (Which of course means I'm going to wind up making a different mistake when placing one of the other traps, since this game doesn't remember where you placed traps outside of the single save slot you get.)
By the way, you're timed during your build-phase. It's a relatively generous timer and I've never encountered it reaching zero, but it exists. So just keep in mind, while I'm wiggling back and forth trying to find the perfect spot for this wall to go down, that I am running out a clock.
I cannot control the camera angle. I can zoom in and out a little, as well as pan the camera left and right, on larger maps... but I cannot change the camera angle, meaning I cannot always see what I'm doing, making it very difficult to line up the perfect spot for the wall to be placed at.
But at last, I do it. I place the wall, save the level, and then release the wave. And huzzah, the enemies do not go through the wall. At last! I load the save and continue placing traps, wandering over to the other side of the map. I perfect all of that, and save the game again, before sitting back to watch my glorious accomplishment... only to find a monster has gone past that same wall I set. Somehow, it's bypassed the wall. I move over to watch carefully, only to find it doesn't happen again.
My suspicion is that, on larger maps, the game will not properly load certain structures you've placed if the camera isn't on them. I have not confirmed this, but I can say with confidence that I have ran the same mission with the same trap placements multiple times, and I've encountered multiple instances of enemies behaving inconsistently.
Meaning it's theoretically possible to have a perfect trap setup, only for enemies to path slightly differently for one reason or another, ruining everything.
Perhaps it's due to Unity fluctuating in framerate. Perhaps it's due to some spaghetti code somewhere. But why is irrelevant - it happens.
This is not to mention how sometimes the inventory button vanishes; how it's finicky to flip through your equipped traps; how some traps seem to have hitboxes which aren't properly aligned with their models... I could go on.
Long story short: Conceptually, a tower defense game with a single wave, in an open environment, without a grid system... it's a cute idea. This could theoretically work. But the walls would either need to snap to geometry, or be much bigger, or the maps would all need to have much smaller hallways. The enemies would need to have arrows on the floor indicating the full path they're going to take, which would need to update as you place traps... or at the very least, have an indicator when they're successfully blocked off. And it *needs* quality of life improvements for its user interface.
This game is frustrating to no end. I felt like I was fighting the game every time I tried anything, and that is not a good feeling to have. I cannot in good conscience, recommend this game to anyone in its current state.
