the concept seems cool and the art style is also pretty cool. I also still had to do 20 attacks on slimes before buying anything assuming there are no misses even though you said the long grinding was fixed. I also think there should be more possible patterns they could have. It would also be nice to be able to use arrow keys, but that's a pretty small thing. there also aren't any decisions to make or anything like that.

you do like 1 damage and I'm not doing the same pattern 20 times to kill 1 slime.
