This is a very cute game with a lot of thought put into it! The gameplay is surprisingly substantial; it has good pacing and some creative dungeon ideas with cool map designs! I also liked the bonus Happy Birthday side story!
The entire game is also filled with references everywhere; from animations, menu descriptions, dialogue and more! If you are a Tempus fan, definitely give this game a go! It made the game feel very earnest and it was funny seeing these things pop up!
I enjoyed this game a lot more than I thought I would and I'll play any other games the creator makes if they decide to make more!
I do truly think this game is very good and it's extremely impressive that it was made by a fan in such a short time frame and for free!! I do have some very minor critiques if you want constructive criticism (contains spoilers):
I think there should be 1 more dungeon and/or boss (optional?) after getting Vesper since you don't really get a lot of time to play with the full party otherwise. I also think repayable bosses would be cool, as that gives you something to do with your save file once you have completed the game. I do understand that this would have taken extra time that you might not have had however, and by all means I think this game is great as it is!
Another thing is that I thought the MP spells were generally cooler and more personalised to the characters than TP skills were (exception is 'Switch to Regis' skill, which is great!). The main character affected by this is Axel. I also found it tricky to build up TP in some cases, so I struggled to get Axel to do something besides a regular attack on most turns. Maybe Axel could have had an MP spell that would allow him to build up TP faster?
Finally, I think you could block off inaccessible areas with NPCs to show that you can't go there yet. I explored the whole map trying to go to places I wasn't supposed to at first (I still had fun exploring though)! But this is a very minor and personal suggestion!
