It was a nice experience after I've learned the controls. The setting is cool and surely is a fun game and can even be improved and expanded. visuals are good and the music too, It reminds me of some of the old flash games. the initial cut scene fits well.
On the things that could be improved there are game's UI (seeing the attack radius and the enemies left, didn't knew when those turrets would stop appearing lol) and the abrupt ending (trying to explain it better in game). Overall it was nice, simple and fun. Congrats!
