Wow, that is a very cute idea! I especially like being launched by the blobapult :D
It would benefit from some short intro/onboarding/tutorial, given it's a bit counterintuitive compared to the classic TD genre :) Also, I think the catapult and the canon should be more powerful since they require way more effort compared to basic towers :)
Yeah I think it definitely has the problem of being a little unintuitive considering some mechanics work pretty differently from other TD games. I think the cannon does scale better than the other 2. And I'm currently thinking I want to emphasize the blobapult as more of a support/mobility tower. I'm thinking maybe make the slow upgrade more immediately accessible and reduce it's damage a bit so its role is more clear.
Thanks for checking it out! I appreciate the feedback.
