Last time I played this my spacebar was broken so I avoided reviewing or rating unfairly until I got a new keyboard, lol. The game is pretty great. I got farther this time than I did last time, being able to reload manually. The upgrades system is great, and the enemies are pretty cool. I made the mistake this time of only upgrading my turrent nonstop, and not the base...well, that didn't go so well :/ lol
The art isn't anything special, but the game's coding seems just about perfect. The game doesn't feel awkward or anything and pretty much functions as it should. I'd say for future works you could improve on your drawings a lot. Other than that, the sounds were all good, and the menu seems okay. I'm glad you added a scoreboard as well, that's always a nice touch in any game that keeps track. Overall a good game. Keep up the good work.
