I'm always a sucker for mech-building games, so I of course liked the concept of this one. It's interesting trying to build your mech with different parts in order to create an absolute monster build.
I would have loved to see more towers that were unlocked quicker in order to get more use out of the diverse options, as well as being able to switch out towers after you placed them. Also, some more challenging enemies and what-not could of also definitely spiced up the game, but I understand that sticking to the scope of game is important so this is just a wish-list of sorts.
Overall it's a nice game with some well put-together art and some banging music and nice sound effects. I really enjoyed seeing my mech towers expand and grow and then absolutely shredding the bosses. It was short and sweet, just how I like them. Keep up the good work!
