My initial thoughts
I really like the opening image
I wish the whole game was voice acted!
I think you set the ratio wrong on itch, i was missing a bunch of ui until I zoomed out a bunch
I was disappointed that I couldn't break the pots by rolling into them, but then shooting them breaks them so you have been redeemed
I think interact with objects should be a different key than left mouse
I don't think I like the "remove all spells" button. Imo, if you think it needs to be in, maybe make is so it needs to be held
I think either there needs to be far fewer of each element in the world, they need to each have an individual number of uses, or they need to have a max range. as is, I'm spoiled for choice. Maybe it's just because it's the first level though.
If you stand where a pot was after you break it, it breaks all the pathfinding.
The goo enemies are not fun to fight on their own. They are the only thing I've seen 20~ minutes in aside from the turret that I don't think I could kill, some variety with monsters that shoot projectiles or dash or anything would go a long way
Earth spell sound is horrible
I think your upgrade system needs a bit more work. Flat linear improvements are fine sometimes, but the gameplay loop isn't compelling enough to make that quite enough imo
enemies have too much health, and there are too many of them with how unfun they are to fight. I've only taken damage ups, with one speed upgrade, and it is a slog to kill the hordes now
I've stopped gaining exp, I don't know if this is intentional
I also I think I lost all my book power ups when I went into the boss fight, but I'm not 100% sure.
the boss fight was a very nice change. I think you should have it start the second phase a lot sooner. phase 1 is very easy to manage.
Overall, A very strong start! keep at it!
Make the kids do more art!
