The star for mistakes is a bad decision to include in the game. You can have a star system for 'perfect' completions but I think you should do away with the 'mistake' thing (people should be allowed to misclick if they correct it) and hiding the options in the settings is a poor choice too.
I loved the game, great play and writing wasn't bad. I do understand this is a love/hate type of game though, everyone complaining shouldn't be playing this game in the first place, as obviously they'd prefer more action-type games or just straight puzzles. I wouldn't even call this a puzzle game, it's straight interactive fiction
How does this game have higher than a 4 rating? I had fun seeing the characters and reading some of their remarks, but the game is entirely P2W and there's no true depth to any of the gameplay. If you DO like the game and sink into it for a long play, you get the memory error and have to reload. 2/5
The key to Day 3 is to hide your other (nail) gunners BEHIND the flamethrowers.
Throw out 3 flamethrowers to start with proper alignment, increase to 4 or 5 and then line up your long gunners BEHIND the flames and do not expose them.
I had Single Flame - Single Nail - Line of nail gunners
So the line should be in the 3rd row. Finished Wave 20 with those 5 flamers and gunners arranged behind them, and also had another first row flamer thrown into each corner (to bring the count to 7 total flamers) when I noticed killed coming as outliers in the corners
