I had fun playing the whole game, the start can be a little slow and maybe a tiny bit frustrating after playing the tutorial, because there you have more stats than the start, making you feel slower than maybe intended.
But the ramp of the skills feel great, from just killing 1 at the time to having a lot of freedom, it feels rewarding! I think the only thing I could say about this part is, the skill tree is locked from moving until you buy one, which can make it hard to buy the skills behind the start button. Outside of that, I didn’t find any bugs or something bad.
I like how the skills unlock slowly, it has a nice variety/branches that at the end you can buy many upgrades at the same time if you play enough. Also it’s nice to see the effect of letters being put 1 by 1, which can lead to a visual error/displacement when it’s colored in another color but it’s ok. Also you can see your maximum progress with the manifold at the center which is a nice touch and I like the shapes after the 1st one.
The sfx and music felt good, never was annoying or repetitive, the variety of enemies is great and actually is challenging to finish the game which I liked, mostly the fast ships are the hard ones when you don’t deal with the shooters.
I had a great time playing this!
