I don’t know what to criticize first, I know it’s just a demo but this game is so scuffed and has multiple questionable game design choices.
The controls off the jump are jagged for the character we play as in every section; Blocking is a completely useless mechanic as the bosses (and some parts of the normal levels) have tons of unblockables that discourage you from using it.
The elephant enemies and drone shooters in 1-3 blend in way too well with the environment, making them genuinely hard to see as they camoflauge with the background while attacking from the foreground, and the price to pay for not seeing that is a strict 1/3rd of your healthbar in the shoot ‘em up sections for some reason (seriously in my opinion the health-bars should either stick to the ones in the beat-em-up sections or have more I-frames entirely, this Mario 1 ass health system makes chain-attacks fatal with little I-frames)
