Hmmm, unfortunately a bit of a mixed impression on this one.
I really want to like this as I find it quite charming. The presentation is really cool with its pastel aesthetic, the characters are goofy and unique, there's all sorts of neat touches like the receipt printing out at the end, and I love the inclusion of a catalogue which reminds me of old-school instruction booklets that tells you all about the enemies and weapons you can get. When the gameplay works properly, you can really get addicted to this fast-paced, almost Warioware-esque chaos of a battle system where you need to react fast to whatever situation comes up next.
However, while I like the game in theory, I feel like it needed more time in the oven as overall it came off rather janky. So many of my deaths felt like they were due to the controls acting oddly, either eating my inputs or my character moving differently than I expected, most likely due to wonky physics or slopes or what-have-you. Plenty of other deaths were due to the level transitioning and having me land right on top of an enemy spawn with no time to react: super unfair and frustrating! Tooltips would wonk out occasionally and display double, and I expected the tooltips to come up if I moused over something instead of standing below it. Also I hated how I needed to wait for the receipt to print out so slowly just to be able to retry (you'd think it'd go faster or be skippable if you click the screen for a fast-paced game like this!)
Furthermore, even if the game worked perfectly, it did feel rather shallow: didn't take long for the levels to keep repeating, both the items/enemies to exhaust the roster and lose their novelty, and I wasn't sure if it was ever gonna build up to something like a boss or a grander goal instead of just looping over and over. The items also felt a bit annoying in that they have so many negatives to them: I get that it's necessary to make the game harder and harder, but it felt awkward when usually a game gets harder by introducing tougher enemies or levels, not by me choosing it.
Definitely feel like there is something cool in here: just needs a bit of polishing up in my opinion!
