Showed Ok premise, but lacked in common areas.
Nice diversity of cannons, directionality and placement mattered.
Waves weren't clearly delinated.
No idea if upgrading was worth it or not, couldn't see stats so had to guess.
putting a retractable menu over a very necessary part of the screen was an excercise in tedium to place and/or upgrade stuff under the menu
no pause feature meant placing stuff and upgrading and trying to keep an eye on when i was getting more money (because it never tells you it just sneakily shows up in bank) was tough
Hit wave forty-something relatively easily like 3rd try.
