Thanks so much for playing!


Thanks for making this video, a really cool TD game indeed!


Thanks for taking the time to make a playthrough; it means a lot!


A very creative idea for a remake that fans of Bloons Tower Defense should take a look at.


Nice gameplay review ZONGE!


Thank you! :)


Of course! Also subbed, might check out some other gameplay vids when done with finals


Thanks a lot! It is great to hear that you are interested in other videos as well, because I was a bit unsure if people only came for one video and never returned :)


Thank you for your review!


Is it really possible to finish all 3 maps on hard difficulty? 


Is it?...



Hope you enjoy the game, nice video!


Thank you for taking the time to play! Really appreciate it!


Very fun tower defense with exceptional art and interesting Norse theming.


I'm enjoying playing Ragnarok TD in its final form! Overall the levels feel balanced, the variety and detail of the scenery is pleasant to the eye, the audio sounds really fitting for the game theme, the narrative innovatively adds depth to a TD type of game, and it brings back good memories of playing BTD4/5/6 when I was younger.
