Fun to play but definitely gets harder the longer you play. **Developer response:** Thank you very much for your review, very much appreciated. If you have any suggestions, please dont hesitate to reach out :) ### 5/5 — Awesome TD *2026-06-02* This is a great free game that doesn’t make you watch ads to play. I don’t think I’ve watched a single ad actually. This doesn’t have tons of towers or enemy types. It’s simple, but fun and easy to play. **Developer response:** Thank you very much for your review, very much appreciated :) ### 5/5 — Cool! *2026-06-01* Great updates thanks **Developer response:** You are very welcome :) ### 5/5 — Classic TD *2026-05-14* This is a fun time waster. Give it a try if you like TD games. **Developer response:** Thank you very much for your review Very much appreciated ### 5/5 — Awesome TD *2026-04-25* This is a great free game that doesn’t make you watch ads to play. I don’t think I’ve watched a single ad actually. This doesn’t have tons of towers or enemy types. It’s simple, but fun and easy to play. **Developer response:** Thank you very much for your review, very much appreciated :) ### 5/5 — Good just a little buggy *2026-03-15* I really like the game style and the simple ui. However there seems to be few bugs that while not awful are annoying. For example, I watched a few ads to be able to afford some permanent upgrades but then the upgrades didn’t work. **Developer response:** Thank you for the review and for reporting the bug. In the meantime I have located the cause of the issue and solved it right away. The upgrade was done, but when starting a new round, the game didn't reload the fresh upgrade (Only increase start coins was affected). Next release with the fix is planned to be released this Friday. Again, thank you very much. Tim ### 5/5 — A great retro game *2026-03-02* Reminds me of games I played many years ago. I’m much prefer this style to the overly busy, crazy graphics tower defense games. **Developer response:** Thank you very much, I have the same preference :) ### 5/5 — RetroTD *2026-02-15* Let me not start this with the gameplay. Tim, the owner and developer, listens to feedback and connects with his community. This game is simple and the classic tower defense. This game is worth a download if you enjoy the classic tower defense feel without the complexity of new tower defense games. **Developer response:** Thank you very much! Very much appreciated. Stay tuned for many more (simple) features that will enhance gameplay and if you have any requests, let me know ## Frequently asked questions about RetroTD ### What is RetroTD?
