I'm sorry, but this game is actually objectively TERRIBLE!
Even the cheapest unit's are WAY too expensive & mana recharges WAY too slowly even with the speed upgrade! by the time a unit leaves, you won't have enough mana to replace it and enemies will swarm by!
The limited choices of placement does more harm then good! So many units have god-awful range and leave at the worst possible time!
Waves are WAY to packed with enemies, making even the easiest levels an RNG nightmare if you want to get three stars, and many levels feel like they weren't even play-tested!
Powerup's despawn WAY to fast, by the time you notice it and move to collect it it's already gone, and in some levels like 3-2 in is literally REQUIRED to get as many as you can or else the level becomes IMPOSSIBLE!
Bridges are WAY to OP, and they make already frustrating levels even more difficult!
I can see the vision, and i desperately want to like this game, i really do, but this game is fundamentally flawed on almost every aspect and is just not enjoyable in the slightest!
