really big fan of this game, the artstyle and audio are done so well, especially the animations on the sprites! i liked the variety of plants you can set up too.
i will say it took me a while to figure out what was going on lol, for a fully fledged implementation of this game a tutorial would be nice.
i see the vision with the implementation of the theme but i believe it could've been done a bit better. there was very little prep time between nights, and i think it would've flown a lot better to have the upgrades either pause the game or happen during the prep phase of the night.
overall though, i actually really loved this game! i found it very fun to play with a lot of character and potential for further development of this idea!
(technical issue btw, this game started really lagging after i got to wave 3 due to the sheer amount of things happening. dont know if it was a browser related issue though)
