I am glad you enjoyed the game so much you would like a sequel, I might look into something like that in the future, I have to admit your words got me so excited that I almost want to do it now... but I have already started on a new project so I will look into it after Project Protoearth!
TD2S does seem like a good game to learn from, I'll give it a go later and drop a comment on the game!
please contact me when you do so
it would be nothing but pleasure to give a few ideas
also happy to make you inspired :>
and hearing the new project... i will love to check it
you walking a path of great possible abilities
also one thing i also wanna mention, the art-style this game has, you know what i like about it? it's simplistic, which makes it actually easier for you to add new enemier/stuff into the game
also try TD2S
great game, this is a way you synergies with upgrades, i wish this game would be more updated, since it's one of my favorite roguelike :> (that i can affort)
and every project similar to it gives me hope, beacuse there's something about seeing how different upgrades interact with eachother... it's... beautifull
imagine being inspired by the TD2S and somehow mix them together, where you get upgrades and depending on how you put them, they do different stuff
i believe in you, i see you great potential my dude
and i am happy that your words motivate you, i will stick here or maybe even become a friend and will support you, your game makes a great time :>
have great day!
