Good spin on the tower-defense formula! I really liked the timed spell-casting process, and I liked the idea of casting 'towers' with such rituals. The only thing I'd recommend is music - Bosca Ceoil is a great tool for making simple chiptunes, and I think that's all y'all would need to give it to bring the game up a notch. Good job, and I can't wait to see what you make next!

I liked the game idea, found the mechanics interesting, it was a good job

All parts of a generic single tower defence game exist. Balance could be better, tier-2 hot summoning is the strongest weapon. It's shots sometimes don't disappear, which makes it even more powerful. I guess it is a bug. Also tier-3 hot summoning is good, but has too short time and close range. The rest of summonings are much weaker. Attracting enemies can make tier-3 hot stronger, but tier-2 weaker.

Graphics and sound are low-effort.

Nice job! I like how it starts to feel more rhythm-based as the game goes on. Like others have said, I'd love to hear more music in your future games (though I can see how this may introduce complications with timing the rhythm of the player actions). Keep it up!
