This game was very fun to play through. The lack of jump was confusing originally, and I definitely had to consult the controls a couple times, but after that initial phase of confusion, it was very smooth. The letters each having different abilities was quite novel, and the fact that I could only use two at a time made for interesting decisions. My main complaint is the D functions as infinite height, as you can repeatedly reuse the jetpack in midair (trivializing R, T, and E) and A made any remaining challenge in the game obsolete (which you can get directly upon getting E) S seems fun for speedrunners, but I found the speed boost uncontrollable. Overall, really fun game, but needs some revision on the scaling of the abilities. (4)
The game's art style is charming, and the map design was very competent. Considering the assets were all outsourced, it's hard to rank much higher than 3, however. Using free online resources isn't a problem, but there's not much presentation to judge outside of those resources, and it feels unfair to give a 5 for resources you didn't make. (3)
The core game loop isn't super novel, but the letter abilities add a well-needed twist to the formula. The attachment to the theme was also very creative and well implemented. (4)
