It may just be that Pikmin 4 just released, but I could totally see you selecting a couple of units to spawn, and then a separate button to “send” them all at once. Likely with a limit so you can’t just brute force your way through. As is, it feels difficult to coordinate an attack.

As for the interface, it was a bit hard to parse at first. A nice touch that I liked was that you could see the exact effect of a unit on your resources as you hovered over them. The confusing bit there was the spell to “burn” towers, since I thought it was a unit. Maybe having the word “spells” next to it would suffice? Or split it into a different bar?

On the aesthetics side, the visuals and sounds really work well together, and the font feels “old timey” but also pixelated to not stand out. Good job!

I have a few critiques. For gameplay, at the moment it is kind of difficult to coordinate your troops. For instance, the most common strategy here would be to send in the big guy to take the damage from the towers and then let the little guys sneak past, but because they always walk at a fixed rate from the moment you spawn them its hard to get them to sync up.
For design I think the game needs more context, I still don't really know what the fire button did besides burn 5 of my souls.
As for something good though, the art was the best part of the game in my opinion, and I can tell that the artist put in some decent time on making it all look nice. Also, I do like the amount of levels you have and how they are structured in the level select screen it looks really good

I sadly had a visual bug that made all text disappear, so the number stats didn't show up and I just could play only by luck, but still it's a great game, I had a lot of fun!

Great game! I had a lot of fun playing it and I really like the music, although I am confused about what the icon on the right end of the list of things you can summon does. My only complaints are that you can do most of the stages with just one demon and there is a big difficulty curve at the end.

I think something that's misleading is that you can pretty much pick any stage you want from the start. The problem is you can only beat later stages with resources you earned from earlier stages, so it seems like they should be played in a linear order anyway. You could either have them unlock in a linear order or just cut out the map screen altogether.

Or maybe it would also work to just give players a set amount of resources at the start of each stage. On my last attempt I lost on the final stage, and I just don't feel interested in replaying all the previous stages again for another try. If I didn't need to start from the beginning, or if there was at least more leniency, it would be less frustrating.

Everything else is a matter of rebalancing and polishing what's there, so I'd say expand on this further.

Nice idea for a game! It's a good start but needs a bit more polish. The map dragging didn't always seem to work very easily. Also the start menu button labels weren't there and there were no numbers where it seemed like there should have been. Keep working on it well done :)
